Another 360......

It looks like a nice build. Cam choice is like socks and underwear. Your choice on what you want or like. That F.I. set up likes a wide centerline. IE 112 or better IIRC.
I particularly like the Crane roller cams for something like this. I think a roller is worth the expense at what your doing. Broader torque curve, hi lifting cam.

I think the heads are expensive myself. But a moved pushrod is the way to go for biggest power gains. I myself would rather look at a Mopar head than the Edelbrock heads at this level in part because of the cam I'd choose. You would need to remove any stock valve gear from the Edel. head in favor of the matched and better valve controling Crane stuff.
So cost, I think, would be in the Mopar heads favor rather than re-working the Edel. head.

I like the Edel. F.I. except when a change of cams comes in, you need to send the cam card and computer chip out to Edelbrock for programing so it works right.
