OEM short rod is marked KA4. No markings I know of on the crank. Take a pic and we will tell you!

This is the second crank I've seen, that the pin hole has been bored, plug pressed in, but not stroked. Is there some reason the plug was put in & then machined back to the STD stroke. The whole idea with the plug pressed in is for the stroking process.
Maybe it was a stroker at one time, still good crank halfs & just converted back to STD stroke.

Neil & Tony thanks for responding. NeilI'm not sure what the story was with that crank, I got that one whit a parts lot that I bought a long time ago. The crank with the #1 on it is the crank that was in my motor, the wrist pin clip came out and the the pin slid over and groved the side of the cylinder wall pretty bad, so iI figured I better rebuild or replace the crank.
thanks for the help
