One other thing I just remembered about the Crane 731. There are two different cores and the cheaper one has broken in a few guys marine engines.
I'd check with Tyler Crocket about buying a kit with cam, lifters, valve springs, retainers, locks, roller rockers, conversion studs, ecu remap, and...
It will for sure be a lot easier buy from one source, you will get stuff that works, and I would bet you'd pay the same or less.

If you buy the Crane 731 or any other grind crane make sure to get the copper core not the black core and heres why.....
