Dart-LS-NextSHP-Stroker427
Our DART LS Next Race 8 Second Dart Short Block is designed for vehicles looking for a strong foundation for high horsepower. This short block is professionally internally balanced within one gram and ready for your big horsepower street or race car. The extra strength of this setup relies upon a SCAT 4340 forged steel crankshaft and set of SCAT 4340 forged steel H beam rods, with arp2000 capscrews, CP pistons in an n/a or boosted design, along with the Dart LS Next SHP splayed 4 bolt main LSX block. All of the LSnext blocks are based on Gen III LS design, but can also be used in newer applications. This is the premium 4 bolt iron block available for LSX based motors and can handle upwards of 1500hp. The included components are safe and reliable for up to 1200 bhp, for higher horsepower applications or heavy boost/nitrous use we have upgrades to better pistons, rings, rods, crank etc. Don't hesitate to ask us about custom internal parts for your exact needs, wants, and application!
