HKE L92 427 waiting to go in... dyno guess? Just got my motor on Saturday. It will be a couple weeks before its installed and on the dyno, but to feed my excitement, how about some guesses as to my dyno #s? There will be no nitrous, so things like ring placement and piston specs were maximized for the NA application.

That's probably at least a 570-580 rwhp build if Erik touches it. Good cam size for a max effort build. Hope your tuner is a master!

When you get this thing up and running I wanna hear what a 427 sounds like (Im in Austin too). If you can get 550+ outta it I might skip boost....

My girl friend is getting a motor by Erik similar to yours, but she will have a much smaller cam.
