TKB, I don't send an engine out without having it dyno'd.....

Jeff, stick with the plan you have. You don't need 650hp. You really don't even need 600. Patrick gets by just fine with 268 hp. However, I can get you pretty close to your 600 number with a hydraulic roller.

A 650hp FE is going to be finicky, and from talking to you on the phone multiple times, you don't want that.
