Bought 5.7 hemi/nag1 out of a cop car. Some questions.

Ya it's been a while, but I threw a comp cam in an otherwise stock eagle with just stock, Chrysler dealer 6.4 springs and made around 480 if I recall. I locked the timing and ran it with a holley hp.

Nice! That's 6.4 numbers.

I would be happy if my 5.7 with a 6.4 cam makes 425 hp. :)
