The brand new genuine GM 6.2 LS3 block is one of the most popular choices when starting an LS performance build. With its 4.065 bore size the LS3 has superior efficiency. The larger bore size increases displacement while increasing air flow past the intake valves. The LS3 has a lightweight yet robust construction making it the perfect recipe when trying to achieve a deadly power to weight ratio. With a finished bore and installed cam bearings, these LS3 blocks are ready to assemble.
