J series porn. Do you know why you often see(at least I do) the engine builder torquing the rods on a block? Because that is a major moment in the build. Many processes had to be figured before the rod torquing moment. The main/rod bearings had to be calculated. The pistons mated to the rings. The crankshaft torqued to the block. The piston rings gapped and placed symmetrically in the engine to transfer and balance the heat. Many crucial steps were taken to get to the moment of torquing!
