9. There are two distinct ways to attach the JE forged blower pistons onto our GM connecting rods. The first is to fit the rods with bronze bushings and then install floating wristpins. This is arguably the best way to accomplish this task because if the engine ever needs to be torn down again, the rods will easily be separated from the pistons. We are an optimistic bunch, so we chose the quicker route and used press-fit wristpins. This method of attachment requires the rest pins to be thoroughly cleaned. The rods and pistons were then set into this rod heater and once they were thoroughly cooked, the pins were tapped into place. The clearance between the piston bore and pin is minimal, so once the parts cool, the pins are locked into place while still rotating easily. View Related Article
