Dart Block 31937111 LS Next Block Aluminum Block, 9.240 Deck Height, 4.000 Bore

Designed from a clean slate approach the LS Next Aluminum block has addressed the short comings of the LS platform and is the ideal candidate for hot rodders, drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts.
