Hendren ?

[F22 RAPTOR]

Well no one answered my question so here we go I know of a rebuild that just happened on a 604 and on e85 it was making 456Hp so come on guys can Hendred do that legal because this Guy did? So what's the #s guys. .........

I've NEVER seen Hendrens claim 456HP from a crate. The most I've seen him advertise was like 410HP before the new heads came out. E85 gives you some more HP, but not that much. The only guy I've seen on here claiming that kinda HP from a 604 is "Dynoman14" and he gets blasted on here quite a bit as a snake oil salesman. Hendrens dyno tests every crate before they go out the door, and they only fix the ones that need it, at least that was what I understood Bill to say before he passed. Unless you were there in the dyno room to see this engine at Hendrens I wouldn't believe it.
