first step is to perform the reverse flow oil system mod. This moves the oil pressure relief valve inside the oil pan, applies pressurized oil to the center main and allows me to run an external oil filter instead of the centrifugal filter on the end of the crank. You have to drill into the side of the block all the way into the center main bearing.
