Eagle H-beams suck if you are putting a blower on it - cause you'll be blowing them through the side of your block. They are only good for 500 hp. Go with ROSS forged dished blower pistons. Talk to the guys at ROSS - call them. ROSS piston are good for 9000 RPM with nitros, so they will handle you blower daily. The rods are another story, but stay away from Eagle. You need rods that will be good for 7-800 hp. Not to mention you better be using a forged steel crank and 4 boltmain. You static compression is only gonna be about 8.5 to one to run a blower. Guess you got about $3K to shell out for a blower, and another $3K to tie up in the bottom end and machine shop work. You just can't slap a blower on any engine, you have to build a blower motor.
