PRI 2015 brought forth lots of parts for the General’s LT1 platform, one of which was front-and-center in the ERL Performance booth.
The company’s new LT1 Dry-Sleeved short-block uses the company’s proprietary sleeve system that’s based around a set of ductile iron cylinder liners that are three times stronger than the OE pieces. Sleeve length is measured at 5.800-inch long, which permits the company to offer stroker crankshafts and enlarge the engine without fear of the piston rocking out of the bottom of the cylinder bore. In fact, ERL’s Jeff Liebert tells us that the engine can be spec’d out as large as 454 cubic inches.
In this particular example, one of Callies‘ Magnum 4.000-inch stroke crankshafts along with Callies Compstar H-beam connecting rods swing a set of Wiseco‘s 10.5:1-compression direct-injection pistons, but ERL can fill the dry-sleeved block with internal components as required by the enthusiast’s application.
For racers looking for more power-handling capability, the company is working on their Superdeck system for the LT1, which will make the sky the limit for serious performance builds using the new platform. The Superdeck system for the LT1 is very similar to the Superdeck for LS engines, which is also profiled in the video above.
ERL has a brand-new website where you can check out their immense range of LS/LT engine products, spec out a shortblock per your application, and even read through some of the technical briefs on the company’s patented Superdeck system and how it fortifies the engine block.
