A stroker kit is an aftermarket engine upgrade that increases the displacement of an engine by using a longer stroke crankshaft. In the case of a 383, the stroker kit typically involves replacing the factory crankshaft with a longer stroke version, along with other components like new connecting rods and pistons that are designed to work with the longer stroke.
By increasing the stroke length, the engine's piston travels further up and down the cylinder, which creates more volume in the combustion chamber and leads to increased displacement. This results in a more powerful 383 small block Chevy engine with improved torque and horsepower. The 383 stroker kit is a popular engine upgrade for performance enthusiasts who want to increase the power of their small block Chevy engine.
If your Chevy 383 engine feels sluggish, consider an upgrade by getting this internally balanced 383 stroker kit. Northern Auto Parts has the stroker kit that will help you get the most out of your vehicle.
