We are looking for some insight on if anyone has put a 356 9 bearing 1941-50 crankshaft in a 1940 Super Eight 356 9 bearing engine. The part numbers are different. But they use the same rods and main bearings. Will this work?

Any info on if this can be done would be greatly appreciated.

Thanks

In using a '47 356 in my '40, the rear end of the crankshaft needed the end either machined and added to. We're talking 1986, so memory issue, but either the end of the crank was beveled or needed to be beveled. As I recall, the '47 had a lightweight flywheel and an automatic transmission. The '40 is manual plus overdrive with a 40# flywheel.

Joe,

The info was greatly appreciated.
