I'm no engine expert as my racing career ended in 1991, but to do what your asking assuming your chassis will be up to the 650hp required @3700lbs to run 10.50's.
Several ways to do it...1. 512 BB wedge with TF 270 heads, 2. 572 with -1 heads both at around 10>10.5:1 would be 2 ways to go and we haven't mentioned a Hemi.
