Dyno a 7.5:1 400? Sure, why not?

I'll second that.

When the time comes I would like to grab a set of E-streets and a small solid roller. Something that can take advantage of the heads flow abilities. 1.6 rockers are not out of the question.
I'm working with the same intake and I have a few TQ's to toy with that work very well. Love the flexable spreadbore. Plenty of CFM.

I like Moparlovers build. 470 HP ain't to shabby!
