Stan,
Which cam? I offer a few. Most of them offer decent vacuum at idle.
A vac gauge is a cheap tool.
Sorry Tom I can't remember which cam I bought. In fact it was probably 6 years ago. If I remember corectly I think you were only offering 1 at the time for a 292. i would have to go ack and look through my paper work.
I'm not even sure my problem is low vacuum. I have a good pedal until I start the engine. Then my pedal goes sloppy. I would think if I didn't have enough vacuum my pedal would stay firm.
Oh, What is idle spark?????? do you mean timming?????
