A lot will depend on what heads you are going to run. Will they be 23, 18,
15 degree? Now I have a 23 degree 434 that is 721hp. It has Brodix Track 1 CNC 227 heads, HVH intake, 15:1 compression, and a 930 cfm Holley, Dart Little M block & Comp Cams cam.

Depending on your budget, we have kits that will make 700-750 horsepower.

If you want to stay with 23degree stuff look into all-pro. You can get sb2 take off's at a good price, but would require a different piston also. But you'll gain a lot of power with that swap.
