Description

The United Engine & Machine Co KB Performance Piston Set is designed for Ford Cleveland V8 gas engines, specifically the 5.8L/351 models from 1970-1974. These pistons feature a flat-top style with a single valve relief and are constructed from hypereutectic aluminum.

This set includes 8 pistons with a 4.000 in. bore diameter and a 3.500 in. stroke. The piston rings have a thickness of 1/16 in. x 1/16 in. x 3/16 in., and the set includes wrist pins and retainers. Application notes specify a 9.206 inch deck clearance, and caution that pre-1971 blocks may not have sufficient stock to clean up.
