If you are a big-block sort of guy, then you are really going to like our smallest rat motor; 540" Cruiser. Using a proven combination of top-quality parts with meticulous machining and assembly, then dyno tuning and testing each one, this engine puts out enough horsepower and torque to melt the pavement with the slightest tickle of the throttle.
Like all Smeding Performance crate engines, the 540" Cruiser runs on 90-octane pump gas and works with either a stick or automatic transmission, even with overdrive. This engine will fit where any earlier model standard-deck (9.800”) big-block fits, so things like headers and other accessories will bolt right up.
