Assembling a SBC crankshaft, main bearings and block. Assembled number 1 and 5 bearing saddles with bearing inserts. 2,3 and 4 saddles had NO bearing inserts. Installed crankshaft into the block with 1 and 5 bearing saddles and new bearing inserts. Put a dial indicator on 2,3 and 4 crankshaft journals and checked run-out. Those three came out ZERO run-out. Assembled and torqued all bearing saddles with inserts. Attached an inch pound torque wrench to the snout of the crank, turned and measured friction. At the low end it was 15 inch pounds and at 180 degrees opposite it peaked out at 35 inch pounds. That is double+ the low end reading. Am I just being TOO pickey?
It seems there may be a slight egg shaped number 1 or 5 crank journal or possibly a bend in the crankshaft? Your thoughts please! Thanks ahead of time.
