I think you would be better suited to either build a 250 or a 292. The 292 crank in the 250 block will work, but as has been already mentioned, creates some issues that really aren't beneficial for dependability and longevity without spending a lot of money. The 292 dyno testing that was done previously yielded right at 300 HP and up to 330 Ft. lbs. of torque, with simple basic components. So getting 250 HP out of a 250 shouldn't be that difficult either. As tlowe mentioned, those dyno tests start next week, so keep watching for updates as it progresses. Welcome to Inliners.
