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 the LS Next from Day 1 as its advantages were glaringly obvious. We have since built a gamut of power including NA, supercharged, turbo and nitrous engines. As usual, we were first in line with pre-production orders for the SHP LS Next and received Block #002 (along with the its photo with Richard Maskin, Dart's President). Dart cut up Block #001 as a first article inspection.
The DART SHP LS NEXT Cast Iron block 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. Unlike its predecessors, the SHP LS Next is directly compatible with many of the OEM parts such as the oil pan, filter and accessories.
The SHP LS Next Block is an ideal starting point for hot rodders, drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts. Its lower price point and inter-compatibility of parts greatly reduces the cost and complexity of building or 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. At BOROWSKI RACE ENGINES, we will be using the SHP LS Next in our flagship 1,000 hp Whipple-supercharged LS7s and saving the skirtless iron blocks for our really big power builds.
