I bought a used b18c1 motor with arias pistons and crower rods so i decided to refreash the block with new bearings and mains have it line honed etc etc but my engine builder wants me to go with the new eagle rods with the 3/8 bolt instead of the crowers with the 5/16 bolt. He says that he useses them on all his high HP hondas what do you guys think? he told me to sell them?
