AC Cars to Build Nine Cobras to 1962 Specifications!

Are you a car enthusiast who has a lot of money? Do you not own a Shelby Cobra? Would you like to? Well, you’ve got a chance. Did you miss the chance to buy the first AC Cobra produced? Most likely you answered yes.

AC Cars – which apparently still exists, by the way – will make nine new Cobras to exact 1962 specifications! They’ll even use the original tooling. While these continuation cars won’t be nearly as expensive as the $13.75 million original, they certainly won’t be cheap – be prepared to cough up at least $670,000 (or 500,000 GBP) for just one.

Autocar reports that these cars, which are called the AC Cobra Mk1 260 Legacy Edition, will be built at AC Heritage near the former Brooklands racing circuit in the UK. The factory is run by AC historian Steve Gray, who just happens to have acquired most of the Cobra’s original plans and tooling.

Each “new” Cobra will be built with an aluminum body, and will have a live rear axle and a 260 cubic-inch V8, just like the first Cobra. AC Cars will offer two colors: the original blue of the first Cobra chassis (CSX 2000, in case you were wondering), or yellow. Each car will be left-hand-drive, just like Carroll Shelby’s personal car.

Over the years, numerous Cobra replicas and continuation cars have been built, most notably a continuation series by Shelby American, but these Cobras are going to be very unique. While most replicas copy the more powerful and faster 289 and 427-powered Cobras, it’s incredibly rare to see one with a 260 cubic-inch V8. Plus, these cars have the distinction of quite proudly wearing the AC badge.

This is CSX 2000, the first Cobra ever made, not one of the continuation cars.

As always, donations are gladly accepted. It can even be the unofficial car for The Unmuffled Auto News!

What to Look for When Buying Used Engine Parts

Used engine parts can be a great deal, if you know what you are looking for. They can also kill your engine. Here’s what to look for in used engine parts. Most of the places that you’d go engine parts hunting are swap meets. Bring a cheat sheet of engine codes and casting numbers with you, or you might end up with a completely different part than you need.

  • Intake Manifolds: Most factory performance air intakes are fairly easy to identify because there is a casting number and date code on them. Cast iron intakes are virtually indestructible, but are fairly heavy. Aluminum intakes offer better performance, but are more susceptible to problems. Look at the thermostat’s counterbore, as it is common for that area to get rusted and corroded on aluminum intakes only. If it’s not too badly eaten away, any good machinist can repair it. If it’s badly eaten away, look for another one. If you really want it, however, the bad area can be cut out, and a new piece can be welded on and machined to the original shape. It’s common to see other problems, and if it looks like it’s been modified, make sure that it was done well!
  • Pistons: Careful with these. Most new pistons are relatively inexpensive, but you can score a good deal on them at a swap meet if you know what you’re looking for. If there’s a full set of them and they’re still in the box, you’ve got a great deal. Get them if they fit your car. If they are used, be sure to clean off all of the carbon deposits from the tops and inspect them thoroughly. Also, check for ring lands and grooves on them – this means that something was wrong with the engine that they came out of, and that they are damaged. DON’T buy those! If they don’t fit your engine, they make great pencil or screw holders.
  • Connecting Rods: Used connecting rods are very difficult to evaluate without the proper equipment. Yes, it’s easy to bead-blast and hone an old pair, but you need to take them to a good machinist to make sure that they are good to put into your engine.
  • Camshafts: If it’s unused, in it’s original box, and has full documentation from day one, you can definitely consider it. When buying used camshafts, it’s very difficult to tell whether it’s a stock, weak camshaft or a high-performance camshaft. Plus, modern camshaft technology has advanced so much in the past 50 years that it’s worth it to just buy a brand-new camshaft. It’ll be easier to get one that’s essentially tailored for your driving style.
  • Exhaust Manifolds and Headers: Exhaust manifolds are sturdy parts, but can be abused and broken. It’s not uncommon to find a broken stud in an exhaust manifold. Luckily, they are fairly easy to remove. Used headers can be a great deal or a massive head ache. Ask the seller what they fit, rather than, “will they fit on my Challenger?” Check the welds and flanges on the headers – if the flanges are warped, they will not seal against the head, resulting in exhaust leaks. You don’t want to be like Freiburger and Finnegan from Roadkill. Also inspect headers for dents and scratches that could have come from bottoming out or from hammering them into place.
  • Carburetors: Have a carburetor cheat sheet on hand when you go looking for carbs. You can determine it’s original application and CFM rating. The overall appearance of a carburetor is a good indicator of it’s health. Rebuild kits are available for nearly every carburetor under the sun, so it makes it a good deal less risky to buy a used carburetor.

The Seven Most Significant Carroll Shelby Cars Ever!

Carroll Shelby was a guy who built cars the way that they should be built.  This meant that every single Shelby creation was a masterpiece.  He is best remembered for the 1963-1966 Cobra, but he also built many more cars that are noteworthy.  The racer-turned-chicken-farmer-turned-respected-tuner was an amazing guy who did much, much more than make fast cars go faster.  After his heart transplant, he started a foundation.  His foundation, Carroll Shelby Foundation helps fund heart surgeries for children.

  1. 1965 Ford Mustang Shelby GT-350.  The Ford Mustang was an affordable musclecar.  It was fast in a straight line, but it wasn’t meant to go around corners.  When Lee Iaccoca called Carroll Shelby in 1965, Carroll Shelby told Iaccoca, “Lee, you can’t make a racehorse out of a mule.”  Yet, the 1965 Shelby Mustang GT-350 was one of the fastest cars of the decade.  It used Ford’s all-aluminum 289 cubic-inch V8, a Muncie M-22 “Rock Crusher” transmission, and tons of suspension and chassis modifications.  It was available through a “Get it Friday, Race it Saturday and Sunday, and Drive it Back Monday” program through Hertz.  The GT-350K was the highly successful racing version.
  2. 1965 Shelby Cobra Daytona Coupe.  The Shelby Cobra is one of the world’s most iconic cars, let alone America’s.  It used a stylish, lightweight British AC Ace body and chhassis, a Ford V8, and way too much fun for one person.  The most iconic Cobra was the 427 Cobra, which utilized Ford’s new, all-aluminum 427 cubic-inch V8 that was designed to compete with the 426 Hemi (the engine Shelby originally wanted for the Cobra).  That turned it into one of the fastest cars ever.  In late 1964, the 427 Cobra enjoyed massive racing success, but it didn’t have enough aerodynamic oomph for the long straights at Le Mans.  So, Carroll Shelby had Peter Brock design the Cobra Daytona Coupe.  The Daytona Coupe made a 1-2-3 finish at Sebring International Raceway, and it then went on to win the same finish at Le Mans, putting it 4th overall behind three Ferrari prototypes.
  3. 1965 Shelby Cobra 427.  Arguably the most iconic Shelby ever built, the 427 Cobra was a monster.  It used Ford’s race-proven 427 cubic-inch V8, and your Pontiac GTO or Chevrolet Camaro RS would run for mommy.  The 427 Cobra was a fairly neutral car in terms of handling, even when you got your foot into it.  Even then, it was predictable. Yet, when those 480 pound-feet of torque kicked in at 6,000 RPM, you’d better be holding onto something and have a lot of road ahead of you.  It tipped the scales at just over 2,700 pounds, and the big Ford V8 made a beautiful sound when you nailed it.
  4. 1968 Ford Mustang Shelby GT500KR.  The GT500KR used Ford’s all-new 428 Cobra Jet engine, which was kind of a loud, torquey boat anchor in stock form, but Shelby had a few tricks up his sleeve.  He took the cylinder heads and manifolds from the 427 racing engine, and raised the redline by 1,000 RPM.  This engine gained almost 30 horsepower just by that.  Car Life said of the car in 1968, “At 6000 RPM, the Cobra Jet will pull a semi trailer up Pikes Peak.  At less than 2000, it wouldn’t pull the petals off of a daisy.”  People still rave over the engine almost 50 years later.  It was docile under 2,000 RPM, but it came alive above that.
  5. 1986 Dodge Omni Shelby GLH-S.  The little Dodge Omni was a pretty decent little car, but Carroll Shelby slapped a turbocharger and suspension upgrades onto this little car.  It started the hot-hatch craze, and it still shames many hot hatches today.  It was a sleeper.  Many automotive magazines said that it would leave two very skinny, long tire marks through third gear.  If that’s not impressive, I don’t know what is.
  6. 2002 Shelby Series 1.  The Shelby Series 1 was the last Shelby to actually be built from the ground up by Shelby.  It used an Oldsmobile Aurora V8, a GM 700R4 transmission, and a Ford 9-inch rear-end.  Many people complained about the fact that it felt like an unfinished car.  You know what?  Let them yammer.  it was fast, fun, and stylish.
  7. 2013 Ford Mustang Shelby GT500.  This Mustang deserves to be on this list.  It was the last car to have personal oversight by Carroll Shelby, and it shows.  Shelby took the supercharged 5.4-liter V8 found in the 2012 GT500, and stroked it out to 5.8 liters. It gained 112 horsepower with the stroking of the engine and other tricks.  It uses Mahle pistons, a Tremec TKO600 transmission, a single-overhead-cam, a special Comp Cams valvetrain, and a big 2.3-liter Eaton supercharger.  The engine only gained about 50 pounds, thanks to extensive use of aluminum and titanium.  Ford claims that it will go 200+ miles an hour.  Motor Trend got one up to 197 mph, but I bet that if it was given enough open road, they would see at least 200.  When it was dyoned, it topped the dyno out at 211 mph, and it was still pulling.
