ok i'm rebuilding my shortblock first time i'm doing this, i'm trying to figure out what size main bearings and rod bearings to get, all the bearings in this motor are fine i just took it apart to replace the rings, do i get the same size bearings that came out or what?

That's about it.

You could also use a micrometer and check the crank size.

you still need to know what bearings came out of it. as far as i know all bearings are maked std. or the amount of undersize. i'd measure the main journals and crank pins and buy my bearings based on the measurements.
