Big Block Performance, Small Block Price: It all starts with a 383 cubic inch block and the legendary Fast Burn cylinder heads, offering an incredible 449 ft/lbs of torque @ 4500 RPM with a smooth linear delivery. The combination of a 4.000" bore and 3.750" stroke steel crank, a stout .509"/.528" lift hydraulic roller camshaft and the now included and installed single plane intake manifold (#809-12496822) produces 450 HP @ 5400 RPM. Chevrolet Performance testing utilized a Demon 750 cfm mechanical secondary carburetor and 1-3/4" primary x 33" long headers with 4" collectors. A dual plane manifold (#809-12366573) can be used but will affect overall peak performance by 15-20 horsepower.
