Thanks to the reduced Chevy rod journal dimensions the only clearance work required is a small notch on the oil pickup tube boss. Also, the tube is moved away from the reciprocating assembly by offset drilling the stock 3/8-inch diameter pickup tube hole to 1/2-inch. SVE designed a special fixture for this modification. No windage tray is used. The simple, but effective Milodon oiling system consists of a 1/2-inch pickup tube, 7-quart pan, and high volume oil pump.
