Superchared 1969 pontiac firebird3/6/2024 ![]() ![]() It gets its power the same way that your water pump or alternator does. A supercharger's power supply comes from a belt that connects directly to the engine. More air means that more fuel can be stuffed in, too, so you get more power from each explosion in each cylinder. By compressing the air, it lets the engine stuff more air into a cylinder. Superchargers offer perhaps the most dramatic increase in horsepower to your car of any aftermarket products. Q: What does a supercharger kit do? Why buy a supercharger? A: A supercharger is a form of forced induction. If you're looking to up the boost past the stock 6 to 8 psi that it comes with stock other modifications will need to be made. It now had the 400 hood, but none of the usual Firebird 400 trim.Q: Does a supercharger kit come with everything you need? Or is there a pre-condition my vehicle needs to meet in order to be able to handle a supercharger kit? A: When purchasing a supercharger setup they are vehicle specific which means it will come with everything needed for a direct bolt-on. It had a flat hood with dual hood tach nacelles (this was how the Firebird 350 HO was supposed to be built, but they nixed the double tach nacelles at the last minute).Īfter they were done running the 350HO, they transplanted in a Ram Air V, and did another test for a magazine. It was also featured in magazines articles, like the cover of PHR. Royal modified this car for class racing, and it became the quickest 350 in the country. Royal Pontiac had a 1969 Firebird 350HO, red with a white tail panel and stripes, and lettered up for Royal Pontiac (and later, Leader Engineering). Not all the transplant cars had to start out as Firebird 400's. Also notice that the drag car has scoops in front of the rear wheelwells. The photo of the two Birds side-by-side shows the 1967 Myrtle Motors drag car, with the nose up attitude. In the process they added the hood, stripes, rear spoiler, and emblems. With the Myrtle Motors Firebird, they most likely started with a 350 car and performed the 428 swap. The 1968 GTO Royal Bobcat 428 I mentioned above was an example where Royal Pontiac transplanted in a 428 engine, pulling out the original 400. If these cars were originally 400 cars why is there no Arrowhead in the bumper? (MotorTrend ad on page 2)? Thought all 68' 400 models had them? Sorry if its a stupid question, just thought it wouldnt make sense, that they would change a bumper for no reason. I am very limited in my knowledge about FGF's but out of curiosity. Here's a rough scan of the 1968 Myrtle Motors Firebird 428 test. If this gentleman has one of the dealer conversion cars, it would be worth a lot of money restored today, as long as he has a rock solid paper trail to prove its heritage. Myrtle Motors also did a conversion, and tried to get in on the Royal Pontiac publicity wagon by having one of their 428 Firebirds featured in the Sept 68 issue of Popular Hot Rodding Magazine (attachments below).Įither way, there weren't any factory 67-69 428 Firebirds or GTO's, and there won't be any PHS invoices or builds sheets showing a 428. There was a 67 or 68 Firebird in a Pontiac Enthusiast or High Perf Pontiac magazine a LONG time that was supposedly a Royal Bobcat 428 Firebird, with dual quads. I'd imagine if Pontiac offered a 428 as an factory option, it would have been around $150-$250. ![]() Motor Trend did a feature article on a 1968 Royal Bobcat 428 GTO, and I believe the cost was around $600 for the swap, plus of course they would get your original 400. They didn't produce any factory 428 Firebirds or GTO's, but yes, some dealers did swaps.
