Some of the Most Amazing American Race Cars

Racing is in America’s blood. We started off racing horses, which is still one of the most profitable forms of betting to this day. We also love boat racing, whether it be sailboats or motor boats. We also love racing planes. It should only seem logical that we decided to race cars when they came out.

Our country has created some of the boldest, most successful and boldest racecars in history. These cars are some of my personal favorites, and they only scratch the surface of America’s storied racing heritage.

Chaparral 2E: Chaparral’s 2D was a very successful racing chassis, the 2J earned immortality thanks to it’s snowmobile-engine-driven suction fans. The 2D was better than both combined. It ushered in the aerodynamics era thanks to it’s driver-adjustable rear wing (which was adjusted via a pedal in the cockpit) and it’s side-pod mounted water cooling system. It was pure Texan ingenuity. Every modern race car owes at least something to the Chaparral 2E.
1967 Gurney Eagle-Weslake Mk. 1: Dan Gurney was a true American racing pioneer. This is what I view to be his masterpiece. He also won a Formula 1 race in this car. That’s about as good as it gets, but I still love this car to pieces. The tiny 11,000 RPM V12 and styling that looks like a shark and torpedo are just icing on the cake.
Lotus 56: It’s not just another turbine-powered IndyCar. It was a car that solidified the basic shape of most high-level race cars from 1967 on out. It sent the cigar shape packing. It also had a one-speed automatic and AWD. While turbines and AWD would be banned from future IndyCar seasons, the shape remained and evolved. Even though it’s got a Lotus name and Peter Chapman modifications, it’s still basically an all-American STP-Paxon car.
2016 Ford GT GTE: There was no doubt in any car or race fan’s mind when this car rained on every other car’s parade at the Detroit Auto Show this year. It’s 3.5-liter EcoBoost V6 has been proven in the TUDOR Championship series, Chip Ganassi Racing has had lots of success racing Fords and is ready for a new challenge, and what might be most important to those automotive fans who like to cook (like me) is the fact that the rear diffuser is big enough to chiffonade an acre of potatoes without trying. The fact that it is dressed up in a very patriotic livery makes it just that much more amazing.
Dodge Viper GTS-R Mk. 1: The original Dodge Viper GTS-R immediately proved that a big V10 is an essential asset in endurance racing. On it’s third outing at Le Mans, the SRT Motorsports team took a class win in 1998. Again in 1999 and 2000. You can’t forget the overall wins at the Nurburgring, Daytona, Spa, and the five (yes, five) FIA GT and two ALMS championships. Plus, the fact that it was incredibly intimidating helped.
Corvette Racing’s C5.R, C6.R, and C7.R: For 17 years, The Corvette Racing team has put three generations of increasingly amazing Corvette race cars on the track. All have had an “.R” designation, except the first, which was a “-R.” They have proved themselves multiple times. 1999 marked the first year of the C5-R, which snatched three class wins at Le Mans (among many other wins). The C6.R took seven thundering liters of American muscle around the world, and won many races. The C7.R just grabbed the GTE Pro class win at Le Mans, and that was one of it’s first races!
Panoz LMP-1 and LMP07: Many, many years before Nissan’s GT-R LM caused folks to scratch their heads as to why a front-engine endurance race car is a good idea, Panoz’s LMP-1 Roadster S and it’s less successful sibling LMP07 proved to the world that an endurance racing prototype does not need to carry their engine behind the driver. Neither car was wildly successful, but the LMP-1 certainly got into a few good battles with the BMW V12 LMRs and Ferrari 333 SPs to snag the 1999 ALMS team championship.
Ford 999: Henry Ford should go down in the history books as a stark raving lunatic (for several reasons) because he took the crude, incredibly dangerous 18.9-liter Ford 999 racecar to 92 mph (the equivalent of somebody taking a car to 300 mph today) – a world record – on a frozen lake. The frozen lake was the only place large enough to get the car up to that speed. It made a whopping 80 horsepower, a lot of noise, and had killed a man a year before. It was a brutish, outrageous car that put Ford on the map, even if he became known for utilitarian and economical Model T’s and the now-legendary 1932 Ford.
DeltaWing: No other American creation has so upset the normality of what race cars should look like as the Ben Bowlby-designed, Panoz-managed, Gurney’s All-American Racers-built DeltaWing. The car drastically reduced frontal area to reduce drag and fuel consumption. It worked, and even sparked a copycat (the Nissan ZEOD RC), even though it didn’t achieve any incredible success.
Cadillac ATS-V.R: Cadillac attained massive success for ten years with the CTS-V.R in the Pirelli World Championship Series. Now it’s the turn for the ATS-V.R to take the reins. It’s got some big shoes to fill. It’s got a twin-turbocharged 3.6-liter V6 making somewhere around 600 horsepower that sits somewhere between the massive fender flares and the huge extractor hood. Between this car and the Ford GT GTE, it looks like most, if not all, future American race cars will have forced induction engines.
Swift 007.i: The year 1997 was a lucky year. The team owned by Paul Newman and Carl Haas stopped running a Lola chassis, and switched to a chassis made by the American company Swift. The car had a Ford Cosworth engine, Goodyear tires, and an all-American driver in Michael Andretti. I should probably mention that it won it’s first-ever race outing. Talk about coming in with style. Oh, and I was born that year.
Shelby Cobra Daytona Coupe: This is quite possibly one of the most beautiful cars ever made, as well as one of the most successful. Carroll Shelby needed to make the already-successful Cobra 427 faster, but that meant he needed a more aerodynamic body. He brought on legendary designer Peter Brock, who helped design the 1963 Chevrolet Corvette Stingray. Brock designed a flowing, muscular body that still looks like nothing else on the track. The result was a smashing success. The car won the 24 Hours of Daytona, Le Mans, Spa, and countless other races.
Dodge Daytona/Plymouth Superbird: Mopar’s “Winged Warriors” made aero cars illegal in NASCAR. That should be telling as to how good those cars were. They packed quite the punch with their 426 HEMI engines and special aerodynamics packages. NASCAR outlawed aero cars after 1970. Buddy Baker campaigned a Daytona through 1970, and Richard Petty had one of his most dominant years in 1970 with his Superbird. It’s also one of the most iconic race cars ever.
1966 Chevrolet Corvette: The 1966 Chevrolet Corvette is one of the best race cars Chevrolet ever had. It had a walloping punch with it’s 427 cubic-inch big block V8, with the code-name L-88. This engine made any car it was in a true monster. It’s still fast enough to show a modern NASCAR stock car how it’s done on a road course. It’s like carving a statue with a hydraulic shovel.

The Evolution of Crazy

Pro Street is a popular form of hot rodding nowadays. It’s also incredibly easy to define, unlike rat rods or Pro Touring. Pro Street is classic cars with the rear wheeltubs dramatically enlarged for insanely wide tires. However, defining Pro Street gets a bit more difficult from there. Is it a fairgrounds car with big dirt tires? A street-optimized race car? A race-optimized street car? Or is it a full-on race car? It can be any and all of those. Pro Street has evolved throughout the years from essentially fairgrounds cars to street-optimized race cars. I’ve taken the pleasure of outlining important years and cars in the evolution of Pro Street. While your idea of Pro Street might differ, or not be there, I hope this helps.

1972: Grumpy Jenkins Pro Stock Vega: Bill “Grumpy” Jenkins essentially ushered in Pro Street with the advent of his groundbreaking NHRA Pro Stock tube-chassis Chevy Vega in 1972. Nobody had ever seen massive tires tucked under a production body before. Yes, the extreme Funny Cars had been using the look for a few years prior, but they had fiberglass body shells, so let’s not count those. Grumpy went all-out groundbreaking by using a completely tubular frame, which allowed him to run those massive 14-inch-wide and 32-inch-tall drag slicks previously reserved for Top Fuel. Every single Pro Stock car borrows heavily from that groundbreaking Vega in 1972.

1979: Scott Sullivan’s 1967 Chevy Nova: No, this beautiful 1967 Chevy Nova was not the first Pro Street car. Not by a long shot. However, it was the first car to get massive attention past a small magazine feature on it. It thundered onto the scene in 1979, just a year after the Car Craft Street Machine Nationals were launched to tire-burning success. It created the perfect test-and-tune environment for Pro Street. Sullivan has been known for setting hot rodding trends with just about every car that he builds. His 1967 Nova was no exception. It may not have been as innovative as his other cars, but it doesn’t make it any less beautiful, thanks to it’s highlight stripe and color-matched bumpers. It even had the perfect stance. Sullivan sold the car in 1984 to Pro Mod racer Ron Iannotti.

1980: Some Tubbed Street Machines: Many street rod builders of the late 1970s became brainwashed by Scott Sullivan’s beautiful 1967 Chevy Nova (see above), and completely redid their cars. Just about every car from this era had the back half of their chassis tubbed, and many builders simply moved the leaf springs far inside the chassis to fit the massive drag slicks. Seeing a car with a Roots blower sticking out of the hood was a must well into the 1990s.

1985: Fully Tubbed Street Rods: The cover of the July 1985 ‘Hot Rod’ magazine announced the “Fat Attack” of fully tubbed street rods. One of the cars on the cover was “Fat Jack” Robinson’s 1946 Ford coupe, painted in a vivid Coast Guard orange. The car was tubbed like a true Pro Street car, but it was intended to thunder down the drag strips of America. His car was the result of the first round of the nostalgia drag racing scene of the time. His car inspired several other pre-1948 fully-tubbed cars. Those cars on the cover of ‘Hot Rod’ showed how the Pro Street look merging into the vast world of street rods. It wasn’t long before you’d look around at a hot rod show and see a bunch of 1940s Ford coupes sporting massive rubber. Unfortunately for Fat Jack Robinson, his car ended up being totaled in a crash at Fremont Drag Strip.

1992: Trailer/Fairgrounds Queens: Dick Dobbertin’s nutso Pontiac J2000 Pro Street car arrived on the scene in 1986. You’re probably wondering why I said 1992. That’s because the trend of taking a lowly late-model FWD car being converted to a fully-tubbed, RWD car started then. It made it OK to build an over-the-top Pro Street car that only looked good, which have now been dubbed Pro Fairgrounds. Why Pro Fairgrounds? The show venue was the only place where these cars could really shine. I mean, who would really want to drive a car with more than 1,000 horsepower and a short wheelbase down a dragstrip? If you want that kind of crazy, buy a vintage Fuel Altered car. This radical Pontiac J2000 started the Dare to be Different movement in the automotive world, by starting battles to see who was able to build a bonkers Pro Fairgrounds car that nobody else had built yet. Soon thereafter, builders came to their senses and started the Dare to be the Same movement, which leads us to our next section.

1992: C.A.R.S. Camaro: Many of the builders of Pro Fairgrounds resented building cars they couldn’t drive. They wanted truly functional rides, not simple street rods with a big block, but cars that had gigantic rubber, big wheelies, and low drag strip times. Detroit and Ohio even started a large movement to build cars that were all-steel-bodied, fully tubbed, go eight seconds in the quarter mile, dress them up with bumpers and various trim pieces, cruise them up and down the iconic Woodward Avenue in Detroit with license plates, and then race them head-to-head all weekend. One of the first cars featured in magazines was the C.A.R.S. Inc.-sponsored Chevy Camaro of Rick Dyer and Danny Scott. That iconic Camaro served as the main inspiration for the ‘Hot Rod’ 1992 Fastest Street Car Shootout.

1993: Mark Tate’s Chevy Camaro: That little Fastest Street Car Shootout gained so much popularity so quickly that it couldn’t sustain itself. The heavyweight champs, the Pro Street cars, were losing to flat-out Pro Stock-chassis cars. Those Pro Stock chassis cars were never meant to be driven on the street, unlike the Pro Street cars. Mark Tate joined the fray in 1993 with his stock-bodied Pro Stock-chassis 1967 Chevy Camaro. Then it was Tony Christian’s 1957 Chevy 210. After Christian, it was Bob Reiger and his radical Pro Stock Chevy S-10. Appeal for Pro Stock/Pro Street cars started to wane. These weren’t cars you could build in the garage for $10,000 anymore. These were cars racking up bills well over $100,000. People wanted fast cars that they could drive on the street for not much money.

2011: “Modern Pro Street:” This is a total niche created in the Pro Street world by those wanting a fast car with all of the modern mechanicals. Cars of this look have a Pro Fairgrounds look, street machine behavior, and sometimes a late-model body. These cars usually have the newest engines, turbos, EFI, and the wheels are usually gigantic with incredible tread. The beautiful Mustang shown here is the 2007 Ford Mustang from Fastlane Motorsports. It has a 2010 5.4-liter V-8 with an old-school Weiand 6-71 blower showing out of the hood.

2012: Larry Larson’s Chevy Nova: This is where Pro Street is now. Larry Larson owns a stunning 1966 Chevrolet Nova that has truly incredible performance. He’s run 6.90 seconds at well over 200 mph in the quarter mile after driving 80 mph on the highway all day. How does he do it? Modern technology. He’s got a bored and stroked Chevy big-block motor with twin turbochargers, EFI, and lots of other amazing technology. He’s able to drive it all day to a drag strip, run incredible times, turn around and go home without killing his car. He’s had a LOT of experience in the drag racing world, so he only uses the best parts. If Grumpy Jenkins were alive today, his mind would be absolutely blown. Mine is.

That’s where Pro Street is, and where it’s come from. These cars have state-of-the-art technology, and they are actually quite streetable cars.

What are Bore, Stroke, Porting, and Relieving?

You hear car guys throw around the terms, “bore” and “stroke” all the time. Most of us don’t know what that means. I do. Here’s what they mean, and how to identify them.

Bore: Cylinder bore is the measurement of the diameter of the cylinders in an engine.

Stroke: Stroke is the amount of movement a piston can move up and down.

A bored engine happens when you machine out the block. For example, taking a 400 cubic-inch Chevy V-8 and boring out the cylinder walls to make the engine displace, say 500 cubic inches.

A stroked engine is simple to build. You just pull out the current internal moving parts, and put in bigger ones. Because bigger is better. An infamous example of this is Chevy’s 302 cubic-inch V-8 from 1967-1969. Chevy took their garden-variety 283 cubic-inch V-8 engine block, and put the bigger 327 cubic-inch V-8 internals in. Voila.

An easy way to put into perspective just how thirsty an engine can be is to remember that a 302 cubic-inch engine will theoretically inhale and exhale 302 cubic inches of air and fuel in two revolutions of the crankshaft. If you punch that engine out (slang for stroking it) to 347 cubic inches, then you’re going to have a more powerful engine. That 347 stroker engine is popular with drifters – it’s based off of Ford’s capable 302 cubic-inch V-8. A 347 cubic-inch engine is 14.9% larger than a 302. So, that 350 horse 302 will have 402 horsepower.

Just stroking an engine for more power won’t solve your problems entirely. A cam (or more nowadays) pushes on the intake and exhaust valves. If you’ve got a bigger crankshaft and pistons, upgrade the cam! You’ll have a far more reliable engine. Upgrading the cylinder heads is also smart.

The nice part about stroking an engine is that the engine remains the same size externally.

Porting: A ported engine refers to enlarging the intake and exhaust ports of an engine. This makes for better and more airflow.

Porting is common in drag racing, especially with the use of nitrous oxide (yes, the same stuff that is used to push out whipped cream from the can). It just makes more room for the air to go in and out.

Relieving: No, the engine is NOT using the bathroom! That would be relieving itself. A valve seat is where the valve is attached to. It’s usually a small mound of metal, but it doesn’t need to be. Relieving just removes the extra metal to make more room for bigger valves.

Here are some pictures of the different kinds of engine enlarging.

This is a bored Chevy big-block V-8 engine block. It’s been bored out from 454 cubic inches to 489 cubic inches. That’s 35 cubic inches more air and fuel this engine will hork down.

This is a stroked Chevy small-block V-8 engine. It displaces 383 cubic inches, rather than 350. Instead of 350 horsepower, it makes 425 horsepower. You can buy this engine from Summit Racing.

This is a close-up of a beautifully-ported Ford 302 cubic-inch V-8 from a 1987 Mustang GT LX 5.0. The larger port is the exhaust port. The small hole is the valve seat.

This is a relieved Ford 221 cubic-inch flathead V-8.

Why Legislation A.B. 550 Matters to Car People

California has recently proposeda new legislation. While that might not mean all that much to us, it should. Legislation A.B. 550 would allow for the owner of a motor vehicle subjected to the rigorous California smog check program to pay a $200 smog abatement fee instead of having to go to the trouble of smogging the car.

This bill would require the payment to go to the Air Quality Improvement Fund. The measure will be considered by the Assembly Transportation Committee.

Currently, the smog check program requires an inspection of all motor vehicles when the car is initially registered, then biennially upon registration renewal, transfer of ownership, and various other circumstances. You can find all of that on the DMV’s website.

The law currently exempts all cars manufactured prior to 1976, and certain other vehicles.

What’s so special about A.B. 550 is that it would allow the owner(s) of a motor vehicle that is required to take a smog test to pay a 200 dollar smog abatement fee IF the car meets the following criteria:

The motor vehicle is 30 model years or older
The motor vehicle was manufactured during or after the 1976 model year
The motor vehicle fails a smog test
The motor vehicle fails a subsequent smog test after necessary repairs were performed

This could mean a lot to hot rodding. Newer cars are easier and cheaper to insure, parts are more plentiful and cheaper, and, since newer cars have the necessary smog equipment, hot rodders can start to build killer smog-legal street cars.

It’s extremely important to me and many others in the automotive industry that we (as in auto enthusiasts) contact the California Assembly Transportation Committee to voice your opinion of A.B. 550.

Here’s how to do it. Email Steve McDonald at stevem@sema.org a copy of your letter. Also, send this to your automotive enthusiast friends! The more people who voice their opinions, the more likely the bill is to pass.

Thanks for listening to my rambling about how this could turn the hot rodding hobby around. If the bill passes, there will be people who abuse the system, but they already do that. I wouldn’t worry that much about it.

I think these cars that are only slightly customized could greatly benefit from A.B. 550:

This bone-stock 1976 Camaro could benefit from an LS-motor swap. Chevy Performance even offers an LS3 E-Rod engine that is smog-legal in all 50 states. You just install the engine and slap on a couple of stickers that let the smog guys know. These second-generation Camaros are popular among hot rodders, and one could throw on aftermarket suspension pieces and nobody would notice.

This is a simply tasteful C-10 stepside. The wheels go well with the dark blue/black paint on the truck. The big visor over the windshield is a cool touch from the 1950s. It would be even better if the owner could put a thundering big-block with EFI on it.

This 1985 Fox-Body Mustang is an early Saleen Mustang. It looks better than the flashier late-model Saleens. It was a performer in the day, but my Mazda3 could beat it to 60, through the quarter mile, and in just about everything but looks. If somebody bought a Fox-Body, got a body kit (Saleen rip-off body kits are common in drifting), put in an EcoBoost V-6 found in the Taurus SHO, this would look amazing, and go like stink. If there was an aftermarket suspension kit on it, even better. This would be a holy terror at autocross and track day events. Plus, it would be a fun daily driver. OK, I’m going to rein myself in now…

The last car on this little list is one I really want. It’s a Chevy C3 Corvette. Let me explain. It has stunning good looks, and would be quite the performer with a modern LS engine under the hood. It’s already been done, and that’s the car in the picture. It’s got an LS3 E-Rod under the hood, and even though it’s a 1972, one could very easily do the same thing to a 1976 or later model.

The World’s Craziest Go-Kart!

Go-karts are fun little vehicles. Some of them can go up to 70 mph – in just a few seconds! Others can climb up hills. Most don’t have Chevy big-block V8 engines, though. Dirt Every Day, a fun off-road show on the Motor Trend Channel has a go-kart with a 454 big-block. I’m pretty sure that that just elevated the host, Fred Williams, to the crazy-maybe-stupid category.

In the previous episode of Dirt Every Day, Fred had an off-road club of college kids called the Poly Goats come and demolish a 1986 Pace Arrow motorhome. For those of you who don’t know what makes it so special, I have one number for you: 454. Nothing else needs to be said. The Poly Goats made mincemeat of the Pace Arrow. By the end of the episode, it was a bare chassis with a 454 cubic-inch V8, a Turbo 400 transmission, and a beefy rear end. That’s a good start for a monster go-kart.

However, Fred needed to build and install all of the necessary components to ensure that this crazy contraption starts, stops, turns, and shifts. However, every go-kart needs to be safe, so Fred turned to his good friend, Frank, who is an engineer. Frank helped Fred out by giving him tips about the rollcage.

After Frank, some of the Poly Goats come to help Fred get the crazy kart good to go. After a long day wiring the pedals, steering column, and shifter, fabricating the wide wheel set, and wiring the engine up, the go-kart is good to go. Fred wisely decides to not drive the go-kart around his neighborhood.

The next morning, Fred trailers both his mini go-kart and his recently built monster go-kart out to a remote ranch for some off-road hoonage. He is going to have a shootout. Instead of him driving both go-karts, he has a couple of Poly Goats come and assist him. They are brave souls.

One of the contests is where the contestants have to see who starts their engine first. The big go-kart wins by a mile. The next contest is a timed obstacle course where the drivers have to go around one or two trees depending on kart size, moving around bottles, and going in between cattle skulls. The tiny go-kart wins. Then, a drag race, as drag races have proven to be popular on the Motor Trend Channel. The big go-kart wins. You just don’t expect a tiny gas-powered go-kart to win against something with a 454. Then, Fred decides to have a tug-o-war competition. Yeah, we all know who won there.

After all of the contests, Fred takes the monster go-kart off-roading. It looks like a lot of fun. Don’t do this at home, kids.
