406 cubic inches
This is a stock style setup, featuring a 3.750" stroke. Whether intended for stock replacement or racing, various levels of compression will allow for improved performance with emphasis on top-end power and high RPM.
421 cubic inches
This is a very mild stroker combination, using a slightly longer-than-stock stroke at 3.875". The result is higher displacement and bottom end than stock, with a very good balance between low-end torque and top-end horsepower and RPM. This makes it a great choice for all types of application.
427 cubic inches
This is the largest stroker combination available for the Chevy 400, using a 4.000" stroke to achieve 434 cubic inches of displacement. This configuration will be more bottom-end heavy than the others, with less emphasis on top-end power. Great for applications where high RPM aren't quite as crucial, such as in street/strip vehicles. Compression ratios vary from low to high.
