If you’re a big-block sort f guy, then you’re going to really like our smallest rat motor; 540 Extreme. 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 a slightest tickle of the throttle. Like all Smeding Performance crate engines, the 540 Extreme runs on 91-octane pump gas and works with either a stick or automatic transmission, 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. You do have to use an electric fuel pump and block adapter for a clutch linkage pivot ball, but other than these two items, everything else bolts right up. And don’t forget our other options such as a high-flow water pump or our high-lustre polish package.
