340 forged crank question

-
I've personally run them cut all the way to fifty thousandths,,,,,,,,,,,federal mogul use to make main and rod bearings that size but I can'trecall the part#
 
Wow, I had never heard of a .050 undercut!! I guess mine should be alright, looks it'll clean up with .020. Nothing like a good forged steel crank.
 
i know clevite has bearings for .030 both rods and mains and i think they may have them for .040-.050 also not sure if that was for the rods or mains however
 
.................I HAVE DONE .060..........if this is a low compression engine off set grind it to gain extra cubes+compression....kim........
