The 1960s were the heyday of the truly cool American car; a time when slabs of sheet metal, chrome and loud exhausts defined cool. Forty years later, every car and every engine from that time period has its group of devoted fans and experts! We at Proformance Unlimited are excited to present you with one of the most icon engines from that time, the Chevy 427 V8.
