EZ Efi is limited to 650 hp.... sounds like you'll be bumping against it with your set up.

I see a couple problems (well, several) but these two jump out:
1) your compression with those pistons and those heads will probably be in the 12:1 range - race gas territory
2) .565 is a lot of lift which requires a lot of spring to control - which kills longevity of the cam.

However, a 280H only has .480 lift with a lobe separation of 110.... so I'm a bit confused at your combo.

Just dyno the thing. That way there will be no doubt. If you don't like the way it reacts, you can swap the cam.
