Prestige Motorsports - GM LSX Crate Engines (Iron)

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, and unique six-bolts-per-cylinder-head clamping capability that enables forced-induction and nitrous combinations of greater than 2,000 horsepower.
