Good luck with that, unless it's a mega block I don't see it lasting long making that much power. Crank walk is one of the biggest issues with the 440 block design above 700HP. Also very hard to believe a wedge that makes 730ish horsepower is doing it at 5600RPM unless it's 13:1 compression with max wedge ported heads and a solid roller camshaft in the .650/270* @.050 range. I would expect heads that flow enough to support 730HP to be lazy, flowing at minimum 360cfm. Somehow I don't see this as a budget N/A build but more of an all out strip, minimum street setup. Sounds like a wild combo though when you are on the throttle!
