Suggestions for the Best Comp Ratio, Pistons & Cam for Street 340

I am about to yank out my comp 20-223-3, but only because it was the wrong cam for my low CR 318 and automatic. It felt like it really wanted to run once on the highway doing over 60mph. But now I want street torque right from idle, not near 2000rpms in an automatic.

And one thing I have learned is that static CR is one thing, but dynamic CR is another altogether. I think you want to be about 8.5 dynamic CR. Google dynamic CR calculator, and put in your numbers. My comp cam put me at only 6.6 DCR, starting with a static 8.2:1 CR.

do yourself a favor and check that out. DCR and cam specs and hardpoints are linked together.
