Here is an example of a recent customer build taking a LS2 block and sleeving it to push the bore to 4.130. This package allows an LS2 car to be morphed into a pumped up LS7 and still retain the compatibility with the stock LS2 base engine.
This package is based around a custom sleeved LS2 block that Livernois Motorsports machines in house on its own 4-Axis CNC machine. This allows absolute precision and ensures the block is held to within just +/- .0001 to the specification.
Once the block machine work is done we utilize our own custom rotating assembly, complete with forged H-beam connected rods, forged custom pistons, stainless steel top ring and napier second, upgraded thick wall wristpin and forged stroker crankshaft. This takes us to a 429 cubic inch size.
The shortlock is then complimented with LSX-LS7 heads utilizing our own custom CNC program and valvejob, along with the FAST composite intake. This package is designed for the ultimate in streetable performance from a large cubic inch LS base. The added cubic inches and breathing from the bigger bore, coupled with the longer stroke and high flowing cylinder head matched with custom camshaft really turn this engine into a beast.
Shortblock, Longblock and Complete engine packages just like this are available to retrofit your LS2 and LS3 equipped car into a big-bore stroker LS7 monster with direct bolt-in capability.
