Let's start from the beginning. We are still lacking a ton of details.


Which Edelbrock intake exactly.
Camshaft you said Edelbrock and then gave us specs on a Comp, so which cam do you have.
Cylinderheads what year and what is you compression? If you don't know tell us the codes on it. Were they modified (bigger valves, some porting).
Ignition what is your current initial and how much total do you get and at what rpm both values with the vacuum port disconnected and plugged.
Is the "EGR" port pulling from full vacuum (sees vacuum at idle) or ported (no vacuum at idle, vacuum once the throttle is opened).
Are you running headers, long branch manifolds, or stock log type.

Please answer all the questions and as througly as possible so that we can make more informed suggestions.

Thanks.
