..what cam are you using?
..detonation?



I'm using the same pistons as Challenger1
Hughs cam 537/545 ish lift
.028 head gasket to get the compression up a little over the .040 factory/Edelbrock suggested gasket.
I run/race pump premium 93 octane no problem.
BUT, the distributor will need to be curved for your combo.

Chris Schwartz 73 Swinger 340 12.451 @ 108.78 73 Gold Duster, needs a plan.
