What do you think??.9.2 or 9.4 given the towing??.I think because you have said keep it low,that your going to say 9.2.Just want to confirm.

Low is good for detonation, although, there are things like squish to consider.

With the higher SCR , mild cam and iron heads, how will the high dynamic compression ratio come into play?

I'm no expert. just throwing these things out to maybe learn something.

.010 in the hole with a 040 head gasket is fine. with smaller cams. any cam for that matter .. you have to watch the cam events is this willl efect the dynamic compression as well as rod length. with a stock head kit head gasket most are .050 so its not hard to be at 070 in the hole with some pistons so i deck the blocks on most sbc its 9.000 to 9.010 deck all stock build s it will move the CR up abit i like the piston not in the hole much if i can help it by tru-decking the block with the BHJ i done many stock and mild builds this way it works for me . on race stuff were allways working on were the piston needs to be in the block
