Hope I have the correct forum. If not, please direct me to the proper one.
What would be a good starting point for setting the timing on a 331 stroker with 10.5:1 compression?
I got this with no build sheet. It's a roller engine with a Comp Cam, but I have no data.
It has vacuum advance. Degrees advance at idle? Advance at 3,000 RPM without vacuum plugged in? Thanks.
