Chevrolet Performance LSX454 Bare Blocks

Delivering the seemingly impossible combination of professional racing-level strength and entry-level affordability, the Chevrolet Performance LSX454 Bowtie bare 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 cu. in. or more, and unique 6-bolts-per-cylinder-headclamping capability that enables forced-induction and nitrous combinations of greater than 2,000 hp.
