512 build

I'm having Joe Sherman build me a 512 stroker for the 67 coronet. Anyone want to take a guess at the dyno numbers we will get.

512 scat assembly
Eddy victor heads 355cfm on bench
Super victor single plane intake
1.6 roller rockers
Comp custom full Hyd roller
-- 242-- 248---590 lift---111 separation
1000 CFM carb
Compression 10:1

Should be on the dyno in a couple weeks. He think 650-700HP
Is it the Joe Sherman in So Calif, if so he is a Chevy guy and you will probably only get about 300 HP. LOL. Hopefully good numbers.
