Like mentiined, other than touchy tip in a 2000 cfm throttle body wont hurt anything on a big motor. I run a scorpion 2000 cfm on my 462 pontiac efi street car and have tested with them on my dyno on a 548 and wasnt no ill effects i can see

I'd go bigger on the cam if 700HP is the goal. Something like

yes the valve train galley is slightly deeper which helps in many ways, valve train clearance, oil control, prevents V/C gasket leakage, and if one was to use a gasket with a spring oiler the spray would hit higher up on the spring... subtle differences make improvements, all in all this is a new casting and I love working with it...
