I would recommend a dial back light with a metal inductor clamp. My old non-dial back has a metal clamp and I never had a problem. Guess I'll use it, along with the damper, which is marked out to 60*.

) and have never had a problem. I have the slightly more expensive dial-back chrome one. I've been very happy with it no matter what, I agree, the dial-back is the way to go. It is very handy, not just for performance tuning, but also on cars that don't have nice timing marks (like my friend's Tercel that I helped with the other day). . .-dath

Kalaway - You're right, at least it's a Vette You can easily get more power out of it, especially if you don't have to smog it where you live. Putting on headers and a free flowing dual exhaust would give you a good bump up, especially with a little tuning of your HEI unit and the carb.
