Do you have a build sheet?

The builder is working on getting that for me. I mean, whats the important stuff? CR, all cam info, heads & valve sizes, and injector size i think would do it right?

Yes, clearances and tolerances would be nice. But I was more curious as to what goodies are on/in it to to make the HP.

Pulling that motor apart, there is no way it was anywhere over 550hp. Nothing special inside. Smallish cam. Stock heads.
