Obviously the 650 and the dual plane worked for you before, so what I'm about to say really makes no difference, but I gotta say that looking at your stats, the two things that jumped out at me was the 3" exhaust and the 3.55's. I just can't help but think you'd do better with 4.10's, or 3.73's with nos. I also would be leary of not having sufficient back pressure to get any torque off the line when you need it.

But, like I said, you already know it works, it just triggers red flags with me. Sorry!

Tell me about the carb (jets / PV / squirters / accelerator pump sizes as well as which pump cams you are using. If the 750 and the single plane are causing your bog, gears would fix it. Also, you're going to need more than a 650 can give you before it's over. How fast did your vacuum come up, or did it?

Hmmmm....

You know anyone with a Predator?

Take care
