Jmark Most good cams come ground as near perfect as possible. The reason for having different slots in the crank gear, is to make very small changes in cam timing if the block has shifted some during its life and things aren't quite as they should be.

They are also used to get more or less torque at lower rpm by change the "timing" of the cam rotation as its aligned to the crank.

Most times, using the "0" keyway is fine. You can check the cam timing with a degree wheel and a dial indicator, but for a street engine, the cams are usually fine installed at "0".

78 monte For every 4deg you retard,the power band is spossa move up in rpm by 200.
For every 4deg you advance,the power band will move down 200rpm.
Sounds like ya got a small torque cam if it idles smooth.
I would just install it straight up.

Should I advance or retard my cam?

I got a new double roller timing set which allows me to advance, and retard the cam. I don't know a thing about whats in the 350, but my old gears seemed pretty slack, chain was probably stretched, hopefully this double roller will help solve that. But I want to know if I will benefit any from advancing or retarding the cam? Or is it even a good idea since I don't know the duration of the cam? It seems to idle pretty smooth, although I don't have a tach, so I can't say at what rpm it idles smooth. Let me know what you think.
