What heads are you running? If they are alloy? The comp can be higher again. I've been running around on 91 octane with 11.2:1 comp.
The cam in question is the same as Jeff's but with a 112 LCA.
I will be running 98 octane.
Heads are 65cc 302's
Block is zero deck
Manifold is Funnelweb
Carb is a Holley HP 750DP
I will speak to COME again tomorrow
