Chevy 383 Stroker Motor

The 383 stroker motor dates back to the 1970s and is based on a Chevy 350 small-block. By lengthening the stroke (piston travel) and boring out the cylinders to reach 3883 cubic inches, it's become one of the most widely used stroker kits and crate engines.

The Chevy 400, featuring a 4.125" bore, was plagued by overheating issues attributed to its thinner cylinder walls. Hot rodders found it beneficial to use a 350ci engine block with a 4.00" (or 4.030") bore and replace the stock 3.48" stroke crank with a modified 3.750" crank taken from a 400. This allowed them to get more cubic inches out of the 350 without all the heat issues of the 400—thus, the 383 stroker was born!

Soon, 383 stroker kits and 383 stroker crate engines found their way under the hoods of hundreds of thousands of performance machines, with many rodders insisting it was the best engine combination for the small block Chevy.
