sbc main and rod beaing help
Hey guys new here. If you don't know what ur talking about please don't answer i would rather have no info than the wrong info. I am rebuilding an early 1970's 350. I have tore everything down. I have checked all the tolerances main and rod and they are all good .02 on both road and main. So I need to order these same bearing but I want to go with clevite this time. So I need to know if these bearing are undersized oversized or what. The first two pictures will be of the thrust bearing and number 5 main. the next couple will be #3 MAIN (which I believe it .04 undersized cause of the arrow pointing down under the .04). Then I will include a couple pictures of the rod beaings. If you guys could help me out on these I would greatly appreciate it.

have your crankshaft jurnals checked ! the size's are all over the place ,this must be a rebuilt engine the jurnal's done right should be uniform size's for rod's and main's .all of one size for the rod's and the main's ..040 is starting to get pretty undersized .you might need a crank kit with standard size's .
