Here is my issue. I got this car on a trade. The guy I got it from traded it for a truck, so he wasn't the builder and didn't know much about it.. He told me it was a 383 stroker with a 750 double pumper. after looking it over after I got it, I think he was either lying, or didn't know much about it... So I had no information about the motor. It ran like crap when I brought it home, and had no get up and go. Spark plug wire broke, oil leaking everywhere, didn't want to start, because the timing was so retarded, (the dizzy was turned 180 degrees so the vacuum was facing the firewall), pcv hooked up with (yes with) the brake booster, vacuum advanced on dizzy to timed port was not hooked up...
What I have that I know is vortec heads, 1.6 roller rockers, 670 street avenger, lunati voodoo cam 10120701 (Formerly Part Number 60101) double roller timing chain, etc. I do not know the compression, piston size, etc. I do know when I pulled of the balancer, it was missing the key. The cam was advanced 4 degrees.
After getting it back together, and timed it at 12 btdc, my total was all over the place, all the way up to 54 degrees. it started up good, and drove ok, but when I hit the gas quickly it wanted to bog on me... I adjusted the floats, idle mixture screws ( about 2 1/2 turns out), adjusted the acc cam, still nothing... I should mention its in a 87 trans am that had the fi, so the pump is in the tank. The guy had a mechanical pump on the motor with that, and NO fuel regulator... I got rid of the mechanical and blocked it off, and hooked up a regulator. I'm at about 4 psi right now... ( I'll adjust the regulator to about 6 psi).
My question is, how can my timing be all over the place??? I have been chasing my tail for 2 weeks now. where I'm at now is I just ripped apart the distributor ( which was new), and replaced the pick up coil. I havent put it in yet, but I just feel like I'm chasing my tail. I know someone that knows about motors would probably have this motor adjusted and running great in an hour, I just want to drive this car and enjoy it before the snow starts to fly....
