    Well, I'll throw this out. Maybe a cam with 240 [email protected] with .500 lift and 110 intake center line, 850 double pump. Intake would be a single plane air gap and water jacketed headers. I would think this would make 450 to 500 hp. I had this combo and it worked well for me. Was in a '72 Kona jet with Basset headers and pushed it to 75 mph.

    Thanks Tim! Sounds like 500 to 700 hp is the ticket.
