More stroke, more size, more cam, more power. More is better. Get MORE!
Chevrolet's engineers continue to refine the classic Chevy V8 for even greater performance and this stroked Small Block is their latest triumph. Improved Fast Burn cylinder heads and a specific high-flow aluminum intake manifold combined with the extra cubic inches from the longer stroke, push horsepower and torque to 445!
The updated aluminum heads feature 2.00/1.55-inch valves, a unique combustion chamber design and LS-style beehive valve springs for greater high-rpm performance and durability. A hydraulic roller camshaft with more the 0.500-inch lift optimizes the airflow enabled by the high-flow head design.
The SP383 is built with a brand-new block featuring four-bolt main caps. It also features a forged steel crankshaft, and that aggressive camshaft mentioned above as well as durable high-silicon pistons. Unique valve covers distinguish the engine from previous versions and it now includes a high-flow, aluminum intake manifold!
Use a Holley 770-cfm four-barrel carburetor (P/N 19170093) to make the most of the engine's capability and reproduce the quoted performance numbers. A distributor, wires, plugs and some additional components are required to finish the assembly – all available from Karl Performance Parts!
