Hi, I was thinking about putting a 360 crank in a 401 block. Would it be worth the trouble & what would be involved to do it?
Thanks Grant

It would be very little trouble - but why? You would need to either change pistons or have some custom made..
Do you want to destroke the 401 for RPM purposes?
An AMC 401 can wind out like hell...

It's doable, but why?

I agree w/CJ, that it would be of little trouble.
As far as de-stroking for RPM potential, I don't see that replacing a forged reciprocating assembly with a cast reciprocating assembly, even of shorter stroke would extend you RPM's by much. I'd be more worried about oiling issues, & valve train problems.

401 = forged
360 = cast
But a destoked 401 would be badd <-BAD WORD->! The upper rpm potential would be

390's had forged cranks also.
