Concept Performance’s New Aluminum LSR Block Can Take 1,500+ HP

When it comes to making massive power with an LS there are a lot of aspects and trade-offs to consider. While the LS is a capable performer right out of the box, it does have its limits when you start to turn things up. Until now, you could only push the aluminum block so far. High levels of boost or raw power would cause the aluminum to flex or deform under high pressure leaving most builders with only the option of a stock iron or LSX block. But what if we told you there was an aluminum block that could provide all of the additional rigidity of iron without the additional weight? Then you’re going to want to check out Concept Performance’s new LSR block.

Inside the Concept Performance LSR Aluminum Block

Unless you lurk around the local IHOP on certain days of the year, there ain't nothing in this world for free. that's particularly true when it comes to building horsepower -- and as the world of LS performance continues to reach new heights via more boost than there are bleeped-out swear words on an episode of Street Outlaws, the price for dragstrip domination is often more than the cost of pistons and rods.

LSR

Reinforced from top to bottom. Features like added cross bracing in the lifter valley, maximized crankshaft saddle radius and a 40% larger footprint from our double crossbolted main caps means the LSR built for maximum performance.
