Hi again !
So I have the crank reground and it’s -10 on the mains and -20 on the rods
Can someone please point me in the right direction to which bearings I need
It’s a Chevy 318 and it’s a 1971 engine
Thanks the crank I have is a 3751841
Thanks

You need to clarify which brand of engine your working on. Bearings for a small block mopar are readily available in those sizes. Check summit or any quality engine builder...10/10 doesn’t bother me but 10/20 I’d get a crank if I’m going to abuse it.. and that’s just me.. in reality it’s probably in spec. Also is it cast or steel crank?

Part number sure looks like it could be a Mopar.

Crank cast/part number is a 318 from late 70’s thru mid 80’s.
