Starting at a dyno tested 600 horsepower, the WARHAWK 427 with 15° LS1 heads has almost 20% more power than any normally aspirated Corvette engine, and comes with your choice of an EFI or carburetor. Want even more power? Get the WARHAWK 427 with LS7 heads (235cc vs. 285cc intake ports) for a whopping 650 HP on pump gas. Not enough? World Products offers the 427 with a solid roller cam in place of the hydraulic rollers and a 13.6:1 compression ratio that requires the use of race gas, good for 700 or 750 HP depending on which heads are employed. Add another 30 HP for optional CNC ported heads!

These engines are based on World Products’ highly acclaimed WARHAWK aluminum block and equipped with a 4340 forged steel crank and H-beam rods, forged aluminum pistons, and high performance rings.
