We may have to go with the 4" arm to get into the numbers then. I had mentioned the 450hp mark as edelbrock had stated in their kit that it would 415 hp engine with their kit. And I know that's probably more of a meaning of "a potential" if all the other components are there. Before we order anything we will do more research to achieve those numbers. I'll get the specs on the cam.

Here's how "I" would approach this. First, IMO, dyno numbers are useless as tits on a boar hog. Nothing more than bench racin fodder for probably over 90% of the people out there. My approach would be simple. Handle it much like the Mopar Performance recipes in the MP engine manual. Decide on a given ET and build the whole CAR to be that quick. "However" quick that is. Just one man's opinion.
