What size Quadrajet? I now the HOlley's are like 650, 750, etc. I think we looked in the Jegs catalog and the Quadrajet started at a 750 I believe.
It does not seem to be getting enough fuel. If you are slow into it then it slowly takes it fine and runs great but if you get on it there is like a starvation hesitation. We have changes jets and done all the adjustments to the carb. I think its a Holley 450 - little guy!
