A carbureted LS engine? That's right. GMP started with an LS2 and put on an LS1 4 barrel intake manifold. This engine is perfect if you want to install a carbureted LS engine in your 57 Chevy or older GM car or truck. Based on the LS2 crate engine, the LS 364/440 uses an aluminum engine block, with a deep-skirt and six-bolt mains, like other LS motors. This LS is built with lightweight flat-top pistons with a 10.9:1 compression, powdered-metal rods and a nodular iron crankshaft. LS6-style cylinder heads flow tons of air and fuel to the thirsty small block. LS 364 cams has lift on both sides of .500 inches. The LS 364/440 is easy to install. The LS 364/440 is rated at 440 horsepower. The GM LS 364/440 is a great mix of new technology with a proven air/fuel induction manifold.
