Been working on a 1990 Chevy k1500 I dropped a Chevy performance 350 cid vortec 330hp in it with a Holley tbi (just a normal one not a sniper or anything) but we’re having timing issues so I came on here looking for a moates apu1 autoprim kit, we’ve been working on it for over a year know and have tried everything in the book, the last thing we’ve done is set the timing at 2,000 Rpm to 32 degrees, it runs the best this way (no backfiring, bogging, or hesitation) but it still does not feel like a different motor, and we do have a fuel pump for a 96 or 7 vortec which can actually support the added hp unlike the stock, and also adjust the fuel pressure regulator spring on the tbi unit
