Post First time w/timing light-

Hello all,

I got my SBC 327 motor up and running thanks to the help of the gang on this site, and now have a question regarding using a timing light. I have never used one before, and want to know the best way to time my motor with it so it runs best.

I have not yet checked my Chilton manual for its specs for this year (1967 327), b/c the motor now has a Crane Powermax cam in it and HEI, and I didn't know if the Chilton numbers would still apply.

Thanks in advance,

CHEV66JB

Well if it's a basic timing light you should have a red positive and black negative clamp that get hooked up to the battery. There should be an inductive pick-up clamp that goes around the #1 spark plug wire and that's about it. What I usually do is mark 0deg., 10deg., and 20deg. BTDC with some white paint so it shows up nice when hit with the timing light. While idling disconnect any vacuum hose to the distributors vacuum advance, aim the timing light, pull the trigger, and see where you are at. Factory specs were about 6-8deg. BTDC. Those were calculated for a stock engine. I would start with 10-12deg. BTDC. You can try advancing it 2deg. at a time and see how she runs. Any pinging or performance drop back her up. How your carb is jetted, combustion temps, etc. will affect how much advance she'll take.

Morris is right. The factory specs go out the window. Probably about 10-12 deg is what you'll want, but it will take some experimenting. Make sure that you plug the hose that you disconnect from the distributor while setting the timing and then reconnect it when done.
