Ford Performance uses only the best parts, starting with the BOSS Modular block, and adding forged Eagle steel crankshaft, forged Eagle H-beam connecting rods with floating piston pins, and forged Mahle pistons. Bored and stroked to 5.3 liters, this short block is precision internal balanced and ready to be finished to your specific application.
