Quote: Did you check with the cam card to make sure you don't have an altered firing order? I'd be surprised if the carbs are the issue. Try another box and see what happens there. Did you put a timing light on it while trying to rev it? Could be that the box is pulling a ton of timing out too.
I'll have to check into the cam specs, don't know on that. No I didn't hang a timing light on it to check to see if it is retarding as rpm builds. I have a 7531 box in my other car. Does anyone know if I can swap them out just for testing purposes? I know it has way more wiring but I am thinking that maybe the plugs are the same but the 7531 just has a couple extra ones??
