Cam advice for more torque from 340

joec said
scr/dcr whatever, chances are he has 10.5-1 actual or thereabouts .
the intake closing is where crank comp is .The cam he has might not be that diff from what he is ordering.comp and other companies rate their measuring points differently. It might be cam advance/dist advance/tuning where the problem lies.

He will be lucky to hit 9.25:1, especially with the Pistons only out .020 and that thick head gasket and heads that have had a light clean up cut. He's nowhere near 10:1. And that limits his cam choices.
