630 Horsepower 418 LS3 Based

Please call 435-628-4300 to find out about options and upgrades and to place your order.

If you’re into road racing the smaller 418 cubic inch engine has shown greater success than even the larger cubic inch 427 and 454 engines. This has a great deal to do with the bottom end bore and stroke, and crank, rod and piston combination. The 418 listed here is dynoed at 630 hp, has a lopey idle, and requires a minimum 2,800 RPM stall converter.
