340 build advice needed

Compression depends on which cam. Make sure you degree the MP cam. I would prefer it to be under 10:1 and run a milder camshaft but that's me. I ran a similar 9.?:1 340 with the '71 intake and carb, a Comp HE268 cam, and headers. Was a GREAT street package in an E body. Would be even better in a car with more gear and 500lbs less.
