Mark, what timing do you run in your ride?
The boys car is 1931 Model A sedan with 460 C6 and 9" (3.55). This spring we changed to closed chamber DOVE heads for a nice bump in compression and a Comp Cam Thumpr cam. Everything I have read says they like 12-14° at idle which seems low on the Mopar side of things. I can try richening it up. It has and Edelbrock AVS2 from his grandpa on it
@Just Ron but I don't know much about them other than the idle adjustments on the front.
