4-Stroke Short Blocks
SBT Short Blocks are all new cases and internals, bored and honed to standard bore (not oversized). Short Blocks are a great way to switch out the lower end of your engine while reusing your head. This includes everything inside the case: crankshaft, rods, bearings, pistons. SBT’s new Short Blocks ship with the head gasket and valve cover gasket included. No core is necessary as all parts are manufactured by SBT.
