Ron is one of the best with these Engines!

I'd check with Eddie Young. He knows these engines well. He's worth the call.

Not many top builders just going to give out their cam info....

Will depend a lot on what heads & the rest of the package, some cam specs might be good for one combo and not another

If i had 575's, this is the route I would go

Eddie Young spec'd my cams and it chopped/idled and ran like a mofo. He sent my blowers off to DMPE also. Worth every penny.

Same here. Call Eddie Young

I used a Crane 16HR00110. .030 pistons, Super Chiller w/3.5" pulley, stock computer. 700+ tq from 3200-4900RPM, 600+ hp from 4400 RPM, max 698.9HP and climbing @ 5450 and the limiter kicked in. Couple hundred hours on them now.

How much spring pressure did you have also did you change the step studs for the rockers..?

Same here. Sounds really good and runs even better! He did a custom grind on mine - assuming others were same.
