The Texas Speed 427 LT2 Stroker Short Block is built to deliver maximum displacement and high-revving performance in the C8 Corvette platform. Utilizing a re-sleeved GM LT2 aluminum block and a forged rotating assembly featuring a Callies 4.000" crankshaft and 4.125" Wiseco pistons, this short block is internally balanced and precision-built for aggressive naturally aspirated or power-adder applications.

With 427 cubic inches of displacement and a rotating assembly rated for 1,000 horsepower, this combination provides the strength and displacement required for serious high-performance LT2 builds.
