I just picked up a 69 camaro with a 327 and it has some issues. It pops through the exhaust and wont rev cleanly. I set inital timing at 16 degs.
Thing is it wont advance anymore than 25 and it starts popping like crazy. Whats does this sounds like?? Timing? Valve adjsutment?

Sounds like a couple of plug wires are reversed. The firing order is 1-8-4-3-6-5-7-2. Referencing from the drivers seat...Number 1 on the distributor is at the 11 oclock position. Number one is the front left. Left side is 1,3,5,7 from front to back. Right is 2,4,6,8.

While your inspecting the plug wires, I'd remove the plugs. It will tell you more about your motor in case the plug wires aren't the cure. If the plug wires are the cause, it will be an educational exercise to help you next time.

Thanks for the reply. I will inspect the plug wires and plugs tomarrow. Also will double check the and make sure all wires are where they should be!
