340 Head/Cam upgrade before vs after with results

That's true! The humidity does creep up north. I myself, living on an island can not escape the steamy water in the late summer. It becomes murderous here late July & August.

Also true.....

Real actual tests with real world builds. No guessing. Bamm! There it is, just the facts.

J.Robb, what do you figure the
RPM intake would do? 10-20hp?

My last build was similar. Same cam & Comp 1.5 roller rockers on a zero deck .030 - 360 with Edelbrock heads, RPM, 750, 1-3/4 Hooker Super Comps.

Those heads on a true zero deck 360 with a Comp 294S I can't see why it wouldn't be a 430-440 hp piece easy. On this 340 I would expect the RPM to be 5-10 hp better with the same in torque--probably not worth it unless torque below peak came way way up. J.Rob
