the connecting rods are 2 piece at the large end(where they connect to the crank) those bolts there need to be A.R.P. or better for good engine life. The heavier duty GM rods have one size bigger rod bold.after market rods are not required for a mild engine build,just meticulous assembly and attention to detail.
