vortec tbi 350 problems
i changed my heads on my tbi 350 to vortec heads and the motor hesitates when you punch it everything is fine if you just drive normal. a little bit about the motor
stock vortec heads
holly 670 tbi
edelbrock vortec intake with adapter
vortec fuel pump
and everything else is pretty much stock
im wondering if the tps is off by a little bit right now it is at .50 closed and a little over 4.0 WOT
also my rapid fire vortec plugs are gaped at 35
im not sure how many turns on the regulator equals what psi but it did not seem to change the problem when i adjusted it.
any help or ideas would be great this thing is really getting to me
thanks

Maybe it needs a tune. Go trough the "budget ..." sticky on top of this forum.
