I'm going to be building a new short block over winter and I can't decide which to go with, a 331 or 347. Also am not sure on compression, was thinking of 10.5:1 NA or keeping it a little lower like 9.5:1 and squirting a little juice. Either kit will be ordered from CHP, I know that, but just hit this little road block before I move forward and I just want some opinions.
Also, I'll be running Edelbrock Performer heads with 1.6 rockers, Trick Flow intake which I already have, and I'm looking into Comp extreme energy cams.
