Do you think that engine in question really made that power at 6900 with those heads ?

Wow interesting engine!

In their defense I think they specialize in white water jet boat racing.......

The White's (company name is their last name - not for white water racing) actually brought ProComp into Ebay. Everything ProComp on E-Bay foryears was them . The engine builder/machinist(Fred) is the Uncle, the parts seller was the nephew. (Skip)

I do hold that against them, but I do not know how good of an engine shop Fred White's is.

I'd trust that dyno sheet about as much as I trust a fart when I have the flu.

LOL. The picture is funny.

At 6900 I come up with 1013hp as measured by the brake, ie: before correction. After correction 1209.
