5 or 6. I had an S-2 clone in the 70's, and it was fine on the street. It
was a poorly made clone however, and wore out in 19,000 miles. I wanted a
well made cam from a reliable source so I replaced it with a tuftrided Isky
Z-19, which is slightly milder than the S-2, in 1985. I still have that cam
in my car. Thinking about your situation, I paid particular attention to my
car as I took a nice drive with it Saturday. My car idles at about 1000 rpm,
and it is relatively smooth at that speed. It is easy to launch, at
1000-1200 rpm, even with a Fidenza flywheel. I have no idea why you are
having so much difficulty, but IMHO, what you have is very streetable and
you should be able to drive and enjoy it.
