small block heads questions

Here's one I did a few years ago:
[ame="http://www.youtube.com/watch?v=j0q0FJW4LcU&feature=plcp"]422" - YouTube[/ame]

422" (.060 over 340 block)
ported 596 heads (similar to J,X, etc but with a better exh port)
16cc dished SRP forged pistons (owner wanted future growth for better heads)
9.8:1 static. Runs on pump 91 w/10% ethanol.
Crane hydraulic H-302-2 cam
Video shows Crosswind - that was replaced by an Air Gap after it was found to be porous. On plain street radial tires it pushes a 3800lbs Challenger with 3.23s to 12.80s 109mph and gets over 17mpg.

Edit - cam specs are 232/242 @ .050, .504/.528 lift. For a 4" engine this is almost an emissions cam that makes 450+ hp and huge torque.
