REbuild Eng UP/Down w/compresion
I am rebuilding my SB. Stock is 11:1 compression.
All the piston kits for 30 over bore are for 10.7:1 or 11.5:1 compression ratio.
Now What way should I go? Any issues with pump fuel going higher? How much HP power difference (everthing else considered equal)

A couple questions...
Running a hotter or milder cam than stock? Cam will affect detonation. Wilder cams can tolerate more CR.
Also, keeping with stock iron heads or going to alum?

Stock Heads, At least the casting part. Rest will be replaced.
CAM, Either stock or I will change it if need be.
Only items for sure is stock Crank, Holly 650dp spreadbore carb, edelbrock performer intake.
