Call Holley, or Comp Cams since you're running their parts and ask them. They'll ask all the right questions and Desk Top Dyno the combo, plus their technical department has some experience with this, and give you a rough estimate. I would say that assuming 10:1 C/R, 450-460HP is about right.

At least we are all on the same page. I was shooting for 450 so thats cool. Thanks for the input. Its not a unique combo so I figured someone would have a general idea.

One thing that caught my attention is the 24lb injectors. Unless you're running a crazy high pressure fuel system like mine, these injectors are too small at that power level. 30lb much better.
