ATK's new Elite Series LS Short Blocks are a step of above the rest. Every engine is a well thought out parts combination that is purpose built for each application.
Features & Benefits
    • Dart LS Next SHP Skirted Block - The Dart block features a full skirt design with a priority main oiling system, steel four bolt main caps and is setup to run a 4 or 6 bolt cylinder head.
    • Dart BILLET Crankshaft - The Dart Billet crankshafts are proven to handle over 2000HP and outfitted with Center Counter Weights. The CCW not only add material and strength to the center of the crank, but they also add balance and stability that counters the jump rope effect under high RPM and increased power.
    • Manley H Tuff H Beam Connecting Rods - Manley's H Tuff Rods have become the benchmark for fully machined high end connecting rods in the performance industry. These Rods include double-ribbed pin surround and increased cross sectional thickness in critical areas; for a connecting rod that will handle higher boost and horsepower levels than a standard H Beam Rod.
    • JE Ultra Series Pistons - The Ultra line combines all the best, most desirable piston features, such as thermal barrier crown coating, lateral gas ports, thick - wall wrist pins and a new forging technology for the ultimate strength. They are specifically designed for Massive Power and Boost right out of the box.
    • JE Pro Steel Rings - The JE Pro Steel Rings are designed to maximize horsepower through precision sealing of combustion pressure. This ring pack will have a carbon steel top ring for high boost applications.
    • Clevite H Bearings - These bearings were primarily developed for Nascar racing, but are well suited for High Performance applications as well. They're especially good for high revving engines and getting the exact clearances needed with consistency.
    • Suitable for a Single or Twin Turbo application!
    • Custom builds available!
