Too much horsepower?

It takes an AWESOME cylinder head to even get close to make that kind of power. I think I'd worry more about TRYING to make that kind of power before I'd worry about easily getting there and hurting parts.
Do you plan to dyno the engine?

Just as a point of interest...I'm working on a fast bracket 440 small block that will make between 800 and 850HP with a single 4 carb and it will cost no less than 23000.00 including the vacume pump.
RPM is your friend!!
We'd love to see it on the pump that's for sure!!
