    Ballpark HP for my 401 help please

    I have a 77 401 bored .060 over
    9.5:1 Pistons
    Comp 270H cam
    Howell EFI
    502-1 casting heads, mildly ported/polished.
    Also has been fully balanced, including the clutch pak.

    Anyone have a ballpark HP number for this configuration?

    If you need more details, let me know.
