5.7 Crank Tight Spot

[tonysrt]

I just looked up in the 2005 manual re: main bearing selection. The crankshaft counterweight has grade id marks stamped into it. These marks are read from left to right according to journal number,1,2,3,4 &5. Main bearings are coded and ID the size of the bearing. The grade markings are A, B,C with B being nominal size, A being undersize and C being oversize. So this may be why your having a little bit of a problem when torquing down the mains. You may have to figure out what size bearing for each journal. The line hone really didn't help if the journals on the crank are different sizes.
