any will work but some have certain cranks in 8 bolt flange only so don't get caught on that
I love Scat cranks but freight from west coast to east coast means we use lots of Eagle--Never a failure and we beat the snot out of them Honest the Eagle has been refined over the years and is a very good unit--need more? Go Callies and sleep better--get a polished unit that looks like Jewelry but... $$$$$$ Eagle can take a beating--800HP on one is no big deal at all---and.....is available NOW Todd at Marsh Performance will ship you one today for a very good price--!!!!!!!!!!!!!!!!!!!!!!!! Service you can't beat
Don't get all hung up in this one better than that one--the builders attention to bearings and such will have way more to do with good service life--No Detonation--timing correct--bearing clearences right for the application and away you go
Try King HP bearings for some happy measuring.
Good luck!
