Classic Chevy Sugar Land is proud to announce it is offering the Chevrolet Performance LSX Bowtie Block in standard deck height (P/N 19260093). Delivering the seemingly impossible combination of professional racing-level strength and entry-level affordability, the LSX Bowtie Block is the next revolution in high performance engine building. This durable iron block casting is based primarily on GM’s production LS7 block, but designed with more material in key areas (including thicker deck and bores) to support displacements of 454 cubic inches or more. Unique six bolts per cylinder head clamping capability enables forced-induction and nitrous combinations of greater than 2,000 horsepower.
Because the LSX Bowtie Block is based on production LS blocks, all of the LS-Series Gen IV cylinder heads, crankshafts, and accessories bolt right up to it. Chevrolet Performance delivers the LSX Bowtie Block semi-finished, allowing you to finish it to your needs. Whether you’re building a “tame” 500 horse street engine for your hot rod or a 1,700 horsepower turbo engine for an Outlaw drag racer, the LSX Bowtie Block is the foundation for an unbeatable combination at an unbeatable price.
