Sounds like you might have got the cam in it wrong when you installed the chain and gears. Might be a tooth off. The computer should be fine with that cam unless you got it to detonate with too high a compression and cheap gas and it is just retarding the crap out of your timming. That q jet carb is a piece of junk. Get a new thermoquad from advance auto for 189 last time I bought one. The q jet is way too small compared to the thermoqaud which was a stock carb for the small block before they got bought out.

You might have a plugged catallitic converter.
