Just installed new.........
Elderbrock heads (mildly ported) in my 94 LT1 6 speed. Mild mod no compression increase. Nice 25 hp gain. Already in place, 53mm throttle body, 1.6 RR's, Vortex air, Borla cats, new Accel 23 psi injectors. Here are the problems.
Occasionally stalls @ idle. Running 50 psi fuel pressure. Little higher than recommended. Some hesitation on acceleration. Fuel mixture is richer.
Some white smoke noticed on acceleration. Runs very smoothly @ speed.
Is excessive FP the issue with the extra valve lift?? Book recommends 41-47 psi for OEM heads. What FP pressure for my setup??
Your inputs please.
