Hello everyone. Me, Andy and Cory, my brother. We share the duties of keeping a 327 running for daily transportation. We have a small garage behind my house here in Hickory, NC. This problem 327 is in a 63 C10, 3 speed. My questions are, what should my idle timing be? I have engine at 820 rpms, manifold vac is steady at 15, holley 600 vac port capped, has a HEI, 350 heads and headers turbo mufflers.
I read on others threads anywhere from 8 to 12 BTDC. Our engine runs bad at 10 and is hard to get restarted after hot. Am I doing this right. 10 degrees on my digital timing light puts my balancer mark at Zero on chain cover tab? Thanks. Andy.
