    How is the best way to find the best timing on a modified motor. Or is the stock timing sufficient? I didn't see anything on the cam card. Do I need to take it somewhere and put it on an analyzer or dyno?

    Dyno would be your best bet. They cam check it as they adjust the timing.

    I read in a "Truckin" magazine that you could fine tune your engine's timing with a compression gauge. It said to move the distributor around and wherever you got the most cranking pressure, is "the" spot! Anybody ever try this? Did it work? I'm gonna try it, but haven't yet!

    I've always set timing on my race motors by vacuum. Advance the timing until vacuum maxes out, back it off a "hair" and tighten dist. there. Always works and is easy to do quickly.

    I agree with Gold Rush. Using the vacume guage method he describes is a very good way to time it.
