Well I am finally starting my engine build for my Regal. I will be building this 3970010 4-bolt main truck engine to replace the stock 3970010 4-bolt main truck engine that is in my Regal right now. I have a brand new SUMMIT (SCAT) crankshaft, with reconditioned rods and SpeedPro Hyper DurOshield .030" over pistons and moly rings for the rotating assembly.
