I've always heard that 420-430 is pretty much the limit on them. The crank was only forged in the manual tranny cars, due to the 1000rpm higher redline.
It would be cheaper to buy a Cobra, rather than build the motor on a Mach 1, and then boost it. A Cobra would be a LOT cheaper and a LOT more reliable.
