Chevrolet Performance 19433035 - SP383 Deluxe Crate Engine - 435HP

With a long 3.800-inch stroke and 4.000-inch bore size, the SP383 will impress you with it's low RPM torque as well as how well it pulls into the upper RPM range. The proven Fastburn cylinder heads are all aluminum with big intake runners and are packed with 2.00/1.55-inch valves. The latest upgrades are the beehive valve springs which allow the SP383 to rev higher and build more horsepower. The resulting 435hp and 445 lb.-ft will keep you grinning for years to come. It wouldn't be right if it weren't built using a cast iron four-bolt main block, a forged steel crankshaft, an aggressive hydraulic roller camshaft. It is topped off with a great looking high flow aluminum intake manifold and beautiful black Chevrolet valve covers.
