Another Guess My HP Question!

When I was playing around with Comp Cams Dyno software I used stock 452 flow numbers I found on Moparts I believe, I'll see if I can dig them up.
Exhaust will be dual 2.5 inch with x pipe all the way back behind rear tires.

Rumble, do you mean you want to know the degrees at which the valves open and close? I had a page bookmarked with the exact specs but since Crane was bought out I cant get to it. It is almost identical to the Comp 275DEH with just a little more duration and lift.

I wish I had written all that down!
