Fits On/Installation Notes:

The ZZ383 delivers Big-Block power with Small-Block efficiency. We use
the sturdy 383 bottom end, including a brand-new block with four-bolt
mains; a forged crankshaft and heavy-duty rods, and finish it off with Fast
Burn cylinder heads to enable 425 horsepower and 449 lb.-ft. of torque.
