A lot of initial advance will smooth out the idle. That cam is really not huge, so I wouldn't expect a real choppy idle. I still think part of the problem is the RPM manifold. They don't really come into their own until further up in the rpm range. Hence the name. What is the lobe separation of the cam? If its 110 to 112 or so that would smooth out the idle also. With 3.55 gears and that cam I'd say a stock converter would work OK. May not be the hot ticket for the strip, but.... Unless its just bad. I'd question the cam installation (Read my latest thread, I'm an expert
) I'd question the intake. I'd question the converter. I'd question the distributor. What springs, is the advance working correctly, weights moving freely etc.
