This assembly starts with a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, known for their strength and reliability in performance applications.

King SI rod and main bearings are included to ensure smooth rotation and proper oil clearance for the crankshaft and rods. This entire package is fully balanced at the factory, saving you a significant step and ensuring smooth operation right out of the box.

Included with the rotating assembly is a 153-tooth flexplate, ready for your transmission. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine build.
