no problem Vinnie I should of stated that we were a little more of a complete rebuild than just a intake and a cam .with the kb pistons and 64 cc vortec heads the scr was at 9.5 .

don't know if the OP is upgrading the rods and pistons .the comp.on those stock 400's were about 8.5 with a dismal quench. heads were junk and a 2barrel carb,not exactly a big HP combo.think I recall f-bird saying he had a high HP version out of a 70 something chevy but cant remember what.
