Sounds like you are dialed in...don't mess with it uness you are just experimenting with it. Is you drive ratio 1.5? What is your RPM at 55~60?

So it sounds like 1000 HP does the deal to get 80 with BBC's. Has anyone done it with NA SBC's? I'm still thinking 850~900 does it with SBC's simply by virtue of the weight savings.

More empirical research required!!

Id try to borrow a set before I invested.

The 4 blades will bite the water much harder than the 3's and the effect can be dramatic.

At 80 MPH I hope you have some sort of external steering.

Yeah that's pretty much perfect for RPM, maybe a labbed set of 28's to keep your rpm the same.
