This 124″ big bore/stroker Hot Set Up Kittransforms a stock engine into a 124″ monster. This kit includes S&S 4-1/8″ bore pistons, big bore cylinders finished in wrinkle black powder coat, a dynamically balanced 4-5/8″ stroke three piece flywheel assembly complete with S&S heavy duty connecting rods and internal main shafts, S&S 640 gear drive Easy Start camshafts, S&S chromoly steel adjustable pushrods, S&S premium tappets,S&S Super Stock 91cc cylinder heads. When installed the kit yields a 124″ engine with a compression ratio of 11:1. Although the engine is .960″ taller than stock, there are no frame clearance problems, and a stock EFI Throttle body will fit because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold. No fuel or ignition system is included. However, for the best results, a larger EFI throttle body, performance intake and performance exhaust are recommended. The EFI system must be recalibrated.
