Maybe I'm deaf, but I've got a shaved, port and polished head bringing
me to 9.5:1 on a 67 engine with a Weber sidedraft and use regular 87
octane and have not heard a single knock. Timing 20 degrees advanced,
champion N12YC gapped at .035 and stock cam. Now the question, why do I
not have a knocking problem, and if I change the cam will I then have a
knocking problem? Right now with the stock cam the car runs a little
rich, and the temperature never even reaches 165. is this all good or
bad.

Thanks
