When Dart introduced the LS Next block in 2013, it opened the door to mechanically reliable big horsepower builds. The design featured a bottom end with splayed billet main caps, priority main oiling, 6-bolt head provisions, longer cylinder barrels and much more. The iron, aluminum, Darton sleeved and billet variants essentially blew the top off horsepower limitations and we at BOROWSKI RACE ENGINES, INC. were all over it from Day 1 as the advantages were glaringly obvious. We have since built a gamut of power including NA, supercharged, turbo and nitrous engines. One recent LS Next creation of ours featured a 4.5L Whipple plus nitrous and water-meth injection shown in the video below.
Enter the DART SHP LS NEXT Cast Iron block. It features a fully skirted design with a priority main oiling system and provisions for stock and aftermarket oil filter mounting while retaining the key enhancements of the LS Next. Designed for high performance and medium duty applications, the SHP LS Next Block is the ideal starting point for hot rodders, drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts. The block has a lower price point and the inter-compatibility of parts greatly reduces the cost and complexity of swapping out an OEM LS. It effectively fills the gap between an OEM block and the high end range covered by the skirtless LS Next.
