Copo 396 375 HP
With the displacement of a classic Chevrolet Big-Block, the lightweight, all-aluminum COPO 396 racing engine delivers power reminiscent of vintage muscle cars, but with the highrpm capability and vehicle balance dynamics that only an LS engine can deliver. An all-forged rotating assembly makes it a durable performer, too!
