need to find a crank with theese specs::
4.050 stroke
440 mains
2.200 rod
mopar rod width
6 or 8 bolt
cell is 615 573 2738, thanks

Can one offset grind a 4.15 stroke crank to have less stroke? I dont see why not, moving the pin up or down should matter.

have to cut to much, most but not all 4.15 cranks have the rod hole to close to the out side, but i think we can up stroke a 3.9? crank. thanks for posting so quick

Contact Ohio Crankshaft company for the one you want made, they have unfinished cores sitting on the floor waiting to be ground usually

Man i'm still looking around and ain't having much luck. But i will keep in touch.

thanks guys, i know will find something.

anyone make a crank with 3.91 stroke and a chry rod journal?

About a week ago, I ran across a Hemi crank with standard chrysler rod pin that was a 4.0 stroke crank. I been looking for the last few minutes, but cant find or remember were I saw it at....
I will looks some more tomorrow...wife's hollaring at me to come to bed...

I have a cracked 4" one with std Chrysler journal but I don't think you want that. Good luck, hope you find one.

what brand was it, or was it custom?

It was a welded stock forged crank. I had Crankshaft specialist do the work back in the late 80's. It was before all the cheap aftermarket cranks were available. I honestly don't remember if the crack was on a main or a rod journal.

thanks, i thought about taking some stroke out of it and buying longer rods, same pistons. but hate to give up anything, car still has to weigh the same 3450.
