We have extended the billet crankcase upgrade promotion. 

To help kick off the new TR/OBR billet crankcase we will be upgrading every piston port engine or long block to a billet case for the rest of the month at no charge. Starts now Saturday the 8th through the end of the month. No codes or anything special you need to do while ordering. This includes engines on sale, not on sale, prostock's and full mod's. Only exception is the 36cc as it's a 2 bolt.
