Description
When it comes to cranking serious torque from the classic Small-Block, it’s hard to beat the 383 stroker combination, which uses a long, 3.800-inch stroke with 4.005-inch bores to generate exceptional low-end pulling power and surprising high-rpm horsepower.
Rock solid base
The 383 Short Block is the base for Chevrolet Performance SP383 crate engines. Compression ratio with 64cc cylinder heads (not included) is approximately 9.6:1.
