Brad already knows the guy I use to dyno my motors, and the type of dyno he has. I have 4 motors with billet heads, all make over 35hp. But I have 1 with a cast head that should make about 35hp. But it has never been dyno tested. The billet headed motor I'm sending Brad already been dyno tested. While the "legal" cast headed contest motor haven't been.
Yes, the modified billet heads I have flow more than my modified cast heads. Which results in more power, because I use bigger matching flow carbs on these billet heads.
