Ford Boss 351 engine
The Ford Boss 351 is a modifed 351 in³ 335 "Cleveland" V8. Created in 1970, it uses the basic four-bolt Cleveland block and crankshaft but both are constructed from high-strength nodular iron. The cylinder head is modified for better airflow and solid lifters. Aluminum valve covers added to the look. The forged connecting rods were shot-peened and magnafluxed for strength, and forged domed pistons gave a 11.7:1 (11.1:1 advertized) compression ratio.
