I just put in GT-40 (y-303) aluminum heads, edelbrock performer intake, 70mm tb, headers, 1.7 roller rockers, new 73mm MAF, and the car feels weaker than it did before I added all the parts...I have an adjustable fuel regulator and haven't messed with it yet, I also have a larger than stock fuel pump...does anyone know why it's running like crap???
Slower than stock!!!

what is the timing set at?
is the MAF calibrated for your injectors?
at the track, my car was bogging down, seemed slow. i upped the FP and got it to a mid-13.... got lots more left in it.

make sure that you give it a some more timing, but with the aluminum heads, the combustion chamber is cooler, so that allows you to run more timing. Stick with it, i'm in the same boat as you. MY car doesn't make nearly the power it should, but i'll figure it out.
