About this part

Product Details

This Eagle rotating assembly gives you the core components to rebuild your Ford 429/460 SCJ engine for serious competition. You get a 4.140-inch crankshaft made from 4340 steel, a set of 6.700-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and a set of Mahle forged pistons. These pistons are a flat-top design with a -3cc dish, and they come with plasma-moly file-fit rings, meaning you'll need to gap them to your specific application for optimal performance. To finish it off, the assembly includes King XP rod and main bearings, designed for high-stress environments.

This is a well-built assembly designed for the demands of racing, including applications using nitrous oxide or forced induction. The 4340 steel crankshaft and H-beam rods are strong choices for handling increased cylinder pressures and RPMs. The Mahle pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion properties for performance builds. Remember that the included rings are file-fit, so proper ring gapping is a critical step during assembly to ensure good sealing and prevent damage.

When building a high-performance engine like this, it's important to ensure all components are balanced and clearances are set correctly according to manufacturer specifications. This assembly is intended for competition use and is not CARB approved, so it cannot be shipped to California. Always consult the detailed installation instructions provided by Eagle and Mahle for proper assembly and break-in procedures.
