Shipping may take a few days. HOW TO CHOOSE COLOR/SIZE If you have an OEM Crankshaft and OEM Rods, refer to the directions in your service manual for the Bearing Selection Table. If using after-market parts, you will need to measure using a Plastigauge or a micrometer and dial bore gauge to determine which size you need. Note: Some engine builders prefer to use Gen2 main bearings in a Gen1 engine. The Gen2 features a slotted oil hole versus the round hole on a Gen1.
