You know that the LS3 is the new small block V8 in the GM arsenal, but you still want more. We proudly offer you the LS376/515, an upgraded LS3 that is equipped with an aggressive camshaft and GM Performance Parts exclusive carburetted intake manifold. Two simple upgrades that add up to 515 horsepower—an 85 horsepower bump over the stock LS3.
The LS3 comes equipped with components that only a few years ago would have been the exclusive property of race engines. The block is a solid 6 bolt foundation that holds together the 4.06” bore by 3.62” stroke rotating assembly. The LS3 heads are high flowing rectangular port aluminium castings. What separates the LS376/515 from the base LS3 is the addition of a GM Performance Parts high performance camshaft and carburetted manifold.
To match the high flow rate of the LS3 cylinder heads GM Performance Parts engineers installed the “ASA Hot cam”. This is a hydraulic roller camshaft that offers up .525” intake and exhaust valve lift numbers and duration @ .50” of 226 degrees intake and 235 degrees exhaust.
The GM Performance Engineers coupled the aggressive camshaft and high flowing cylinder head design with the new carburetted intake manifold specific to LS3/L92 heads.
