The engine block bottom end and rotating assembly makes up the base for any high performance or racing engine. The components chosen for use here can make or break a project. These engine components affect ultimate power, reliability and longevity. It is recommended that you carefully select your rotating assembly components to meet your performance goals.
The bottom end is not the place to cut corners as any failures in this area, generally lead to very expensive repairs. We recommend building the best possible bottom end assembly that your budget will allow. A properly assembled rotating assembly will allow you to focus on the camshaft, heads, valve train, intake and exhaust systems, etc. when searching for more power. A well built short block assembly is a long term investment, but installing parts in this area which are insufficient to handle your power goals can lead to disastrous and costly problems. Installing high quality parts can lead to many years of enjoyment from your high performance powerplant.
