If you’re looking for a small-block Chevy that makes big-block power, we’ve got the engine for you! For the ultimate GM Performance Parts small-block crate engine, choose the ZZ383‘a combination of Fast Burn aluminum performance heads and a 383" stroker small-block that can add up to 425 horsepower and 449 lb.-ft. of torque.
A carefully engineered balance of torque-producing bottom-end power and horsepower-inducing Fast Burn cylinder heads combine for the ZZ383/425’s stellar performance statistics. The Fast Burn heads have large 2.00"/1.55" valves and specially designed chambers that draw in lots of air and fuel, burning the mixture quickly and completely.
It’s a combination that generates great mid- and high-rpm power, which, when combined with the 383 cubic inch displacement, creates an awesome all-around performer.
The ZZ383 has a specially modified engine block and 3.80"-stroke crankshaft, which produce 383 cubic inches of pure performance. The reciprocating assembly is comprised of heavy-duty components including a 4340, nitrided, and induction-hardened forged crankshaft, and unique, heavy-duty powdered metal rods. It’s 425 horses of bulletproof performance.
With the ZZ383/425, you get the power of a big-block with the size and weight of an aluminum-headed small-block.
If you’ve never driven a car with a stroked small-block and the top end components to support it, now is your chance!
