Description Technical Specs

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 Pro Series I Beam Connecting Rods - Manley's Pro Series I Beam Rods have become the benchmark for fully machined/billet style high end connecting rods in the performance industry. These Rods have a heavier beam for forced induction applications.
    • 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.
    • Calico Coated Bearings - This dry film lubricant helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt. It is specifically engineered to withstand the extreme conditions of High Performance engines!
    • Suitable for a Single or Twin Turbo application!
    • Custom builds available!

5 of 5 Good work fellas!! May 31, 2022
Reviewer: Clint Bodie from Opelika, AL United States  
I recieved my 427 shortblock and it looks great. Can't wait to finish it and get some results. Price was untouchable and even got a free upgrade on the rods due to nonavailability of the normal rods associated with the package. I'll be a repeat customer.
