Turbocharged Gen III Hemi Engine

As a Chrysler guy, Bob Hess always wanted to put a Gen III Hemi into a Ford. When he got this 1982 Mustang as a roller, he worked alongside Big 3 Racing to turn it into a formidable drag car and street car. Check out what makes this Hemi special!

As was the case with so many of the cars seen at Sick Week, this Ford Mustang was one that stopped us in our tracks to take a longer look. And, I’m glad we did, because this 1982 Ford Mustang had a bit of a surprise under the hood. Rather than the Ford we were expecting to see, this Mustang rocks a turbocharged Gen III Hemi engine.

We spoke with owner Bob Hess during day four of Sick Week, when competitors were getting ready for a day of racing at South Georgia Motorsports Park. Bob worked alongside Big 3 Racing in Cleveland, OH to complete his car and engine setup. He was racing in the A Group (8.50 and faster) and competing within the Modified class. As for putting a Hemi in a Ford, Bob said he’s always wanted to do it.

“I always wanted to put a Gen III Hemi in the Ford because everybody puts an LS in them and I’m a Chrysler guy,” Hess says. “When we first found the car, we got it as a nice roller. We had it painted and did a bunch of other updates to it. We started with a 2018 2500 Ram 6.4L and used Molnar rods, custom Wiseco pistons, Brian Tooley Racing spec’d the cam, we did some mild port work on the heads, installed bigger valves, a set of PAC springs, Manton rockers and Manton pushrods, and reused the stock crank, block and heads.”

Looking at what is a pretty clean engine bay, you can’t help but notice the sizable turbo Bob paired with his 6.4L Hemi. He’s utilizing an earlier X275-style 88mm turbo, and also has a Shearer Fabrications intercooler and a Holley race intake manifold modified to put a Ford throttle body on it. The engine is controlled by Holley Dominator EFI.

“The car was built by Big 3 Racing out of Cleveland, Ohio and it was tuned there as well,” Hess told us. “We’re able to get 1,230 horsepower to the tires on 23-lbs. running on C16.”

That equates to being able to run mid to high 7-second 1/4 miles. In fact, Bob said his goal for the Sick Week was to have a 7-second average. He started the week strong with a 7.85 at 172 mph in Bradenton. However, he wasn’t able to get ahold of the track in Gainesville and turned in a 9.13 at 177 mph, which ultimately hurt his 7-second average chances. At SGMP, where we spoke with Bob, he ran a 7.69 at 180 mph, and then backed it up at Bradenton with another 7.69 at 178 mph. Overall, he had an 8.09 average, just missing 7-seconds, but that didn’t mean no fun was had.

“Sick Week has been great,” he says. “We’ve had little to no issues. It feels a lot less brutal than Drag Week because the drives are just a little shorter, so it’s a lot more enjoyable because you’re not rushing as hard.”

Whether you’re a fan of a Hemi engine powering a Ford or not, it’s pretty hard to deny that this is one cool car!
