About the 383 Stroker Crate Engine

The 383 stroker uses a 350 Chevy block with a 3.75-inch stroke crankshaft and a slight overbore. The longer stroke builds torque throughout the rev range, giving strong pull from low rpm without needing big camshafts. Because it keeps the same external dimensions as a standard small block Chevy, the 383 stroker crate engine fits wherever a 350 fits.

It suits Chevelles, Camaros, Novas, C10s and street rods where owners want classic looks and more power.

Before You Buy

• Ask for the build details, including heads, cam and compression ratio.
• Confirm the fuel system type, distributor and accessories.
• Choose a transmission and torque converter suited to the torque.

Installation Tips

Prime the oil system, set timing and tune the carburetor or EFI. Follow a cam break-in procedure if the engine uses a flat-tappet cam.
