Just had a few questions if you have.
i didnt do it but i did quite a bit of reserch on it, and talked to several people who did, and i decided against it. what are your questions?
Was wondering what size TBI, cam, if they bought a chip.
use the 454 throttle body with either the stock 350 injectors (55lb) or the 9C1 cop injectors (65lb). the 454 injectors are too big. i know the edelbrock (non vortec) manifold has bores big enough for the 454 throttle body, but im not sure about the GMPP tbi/vortec manifold..... maybe go with an edelbrock vortec 4bbl manifold with an adapter?
you could use the 350 throttle body, but the 454 one flows alot better.
call up Comp cams, tell them what's in the engine & injection, and what you wanna do with it, and they'll build you a cam for your needs. then, call up Brian at TBIchips.com and he can burn a chip for you if you dont wanna burn your own.
Ive done it on my 383. Pm me if you have any questions.
