Edelbrock offers a Torker II intake with the injector "bosses" cast in, specifically for the use of EFI on the Pontiac. Enderle and Ron's Racing (Tucson) both offer very nice throttle bodies large enough to "feed" the big Pontiacs.

While EFI offers more efficient operation, and using all the modern electronic engine "mamangement" stuff, you can improve the fuel economy of the Pontiac, it won't make any more (if as much) power as a well-tuned carb system. Same is true of your buddy's LT-1, but he won't wanna hear that... This is a fairly common misconception about the fuel systems. From a "raw power" POV, it's hard to beat a good ol' Holley. One of our customers had the "ProJection" system on his 461. It was "dried up" at 5,600 RPM, about 800 RPM below "peak power". NOTHING he tried provided enough fuel to feed the monster. And it was fairly "mild" at about 550 HP.

There was a '69 Firebird at Pontiacs in the Park last year, with a 461 CID Pontiac, Procharger/Holley combo that goes 8.70s (1/4 mile) on 93 octane. Can his LT-1 do that? Doubt it... True, a 383 Chevy is "smaller" than the aforementioned Pontiac. BUT.. It IS a "Pontiac", so CID is of no concern here. When he removed the Pontiac and put a Chevy in there, "all bets are off' regarding displacement. I've seen plenty of 502s in Camaros get hosed down by this and other similar Firebirds with real Pontiac power.

Rather than worrying about "slapping" your bud, just build a solid Poncho. It will do all the slapping necessary... (:-
