Description

This high-output 427 c.i. Small Block Ford–compatible BluePrint Engine delivers 541 horsepower and 519 lb-ft of torque. It's designed for aggressive street builds, restomods, and performance enthusiasts seeking a reliable powerplant with serious horsepower and torque. It's built around a 9.5-inch deck height Windsor-based BluePrint high-strength cast iron block with a 4.125-inch bore, 4-bolt main caps, a one-piece rear main seal, and a forged rotating assembly. It features CNC-ported BluePrint Engines aluminum cylinder heads and a matched hydraulic roller camshaft for exceptional airflow and a broad, responsive powerband. With a 10.0:1 compression ratio, this engine is optimized for 91+ octane pump gas. It is backed by BluePrint Engines’ 30-month / 50,000-mile warranty. The 427ci Small Block Ford has achieved modern legend status through its use in top Cobra and Cobra replica builds, where it's known for massive power in lightweight chassis. It weighs significantly less than a traditional big block, enhancing front-end balance, handling, and braking.
