    Manufacturer's Part Number:

    Delivering the seemingly impossible combination of professional race-level strength with entry-level affordability, the LSX Bowtie Block is the next revolution in high-performance engine building. This durable iron block is based primarily on GM's production LS7 block but cast with more material in key areas, including a thicker deck and bores, to support 454 cubic inches or more. Unique six-bolts-per-cylinder-head clamping capability permits forced induction and nitrous combinations of greater than 2,000 horsepower.

    Because the LSX Bowtie Block is based on production LS blocks, all LS-Series Gen IV cylinder heads, crankshafts, oil pans, camshafts, and accessories bolt right to it. There's a tall deck version to build larger engines, and Chevrolet Performance even offers the LSX Bowtie Block semi-finished so you can do it your way. Whether building a ''tame'' 500 HP street engine for your hot rod or a 1,700 HP turbo engine for an Outlaw drag racer, the LSX Bowtie Block is the foundation for an unbeatable combination at an unbeatable price!
