that is a cast crank, i would not run that me self, it should fit, but i'm not sure how the it will like new style ignition , as far at ive ever seen, all 56ers came stock with a forged crank, heavier but stronger than cast..............

OK, I know you are spinning your Engines hard but would you considder a cast crank for some thing not meant to spin higher than 6500 or so RPM? 4-spline 56ci cranks are not easy to find here either I see an input shaft adapter in near future, Think I can locate a donator shaft for it

That rust on the taper will cause a problem holding the flywheel, you need to get that polished.

the early 75hp had a cast crank, and skinny rods, some liked that setup best, said it pulled better. is lookin like she needs a buff.

Think I Will be able to sort the rust on the taper with electrolytic rust removal and a buff. Just want to make sure I could use it before I put any work into it. Thanks for the heads up!
