Rough Idle
Hey everyone, I have a problem and need some help.
I have a 350, rebuilt 30 over, with a RV cam, Edel. 1406 carb, new vacuum can. Heads were done also. Oh, and I have headers and an Ignitor. I can't get it to even out at idle. Will it ever smooth out with the RV cam? What degree BTC should I aim for before messing with other stuff. I have cured the vacuum leaks and all the plugs are firing (plugs look they way they should). Any suggestions? Thanks everyone. Ro

Did you get the intake on smoothly without damaging the seal front and back? Vacuum leaks can make it hard to get a smooth idle.
