Pontiac Firebird 1978 Description

WOW!!! THIS A REMARKABLE PIECE OF PONTIAC HISTORY PLUS AN EXCEPTIONAL CAR!!!! INCREDIBLE READ!!! VERY RARE FIND!!!


1978 Trans Am with 9,710 DOCUMENTED miles, UNRESTORED beauty with history and documentation (Leader Automotive, George DeLorean).

Up for sale is a '78 Trans Am with 9,710 original miles. It is finished in original paint, Mayan Red, original black velour custom interior, power windows, tilt, AM/FM stereo radio, electric rear window defroster, and WS6 special performance package, all in excellent condition.

Now things change.

The original owner had special ordered the special WS6 package car and had it shipped to Detroit, MI. From there it was sent to Troy, MI. All this was done with the full intent of having the original engine removed and having Leader Automotive build a custom built Pontiac engine. Within a week of receiving the car, he took it to Leader Automotive and had it turned into a sleeper. The outside maintained its original appearance but a monster custom engine underneath, designed and built by George Delorean, brother of John DeLorean of Pontiac Motors. George Delorean is the renowned, legendary engine builder that owned Leader Automotive.

George Delorean, pulled the Pontiac 400 and replaced it with a custom built 428 block with 455 HO heads (stamped 7F6) and a Holley Street Dominator manifold, Holley carburetor, Round Port Hooker Headers (Super Comp) with 2" primary, 3.5 collection, were installed with a free flow exhaust system. The original TH350 transmission was pulled a TH400, with a shift kit, was installed. As well as, a 3000RPM, Stall Converter, and additional external oil cooler. The rear end was changed from a 323 post tract to a 410 gears set. In the beginning, the car had a solid lift cam but was later changed to a hydraulic lifter to provide better driving ability.

It is wild the way we happen to come across this car because it was really just sheer chance, as we weren’t even remotely looking. To find a car that is in such fantastic condition, originality preserved, unheard of low mileage, with a custom built George DeLorean engine…. Just wow! Other than the drive train, the car is in original and pristine condition. The car was originally under coated and also has the Ziebart treatment. Now due to the car being stored for over 25 years it had developed some oil seal and gasket leaks, so the engine had to be pulled. We cleaned up the engine bay and degreased it. While the engine was out we cleaned and degreased the engine, replaced the gaskets and seals, then painted the engine the correct Pontiac blue. We cleaned and polished the original installed Moroso valve covers and oil pan. Also we replaced the exhaust, as it had seen its days sitting for 25 plus years, and the headers, due to one being damaged. We replaced the tires with a new set of BF Goodrich Radical TA's RWL 255/60/15.

We have all of the receipts from Leader Automotive and George DeLorean, of this transformation, including the plaque that was installed on the cowl support by LEADER AUTOMOTIVE, Troy, MI. We have the original build sheet, found behind the back seat, in original, perfect condition. We also have the PHS Documentation and have spoken with all the previous owners and Mr. George DeLorean, personally. This car runs and drives so perfectly and everything is still like new. Even the clock still works!! It is a neck jerking experience, so hold on.................
