Street Series Details & Specifics
Main Bearing Clearances
Main bearing clearance is carefully set on each and every engine. Ensuring proper bearing clearance, along with proper bearing crush are critical for engine performance and durability.
Rod Bearing Clearances
Another critical area of the engine is the rod bearings and setting rod bearing clearance. In order to ensure the correct rod bearing clearance, along with the correct bearing crush, we go through and measure and set every rod bearing clearance, on every engine we do.
Block Deburr & Radiusing
Each engine is carefully hand deburred to ensure that stress risers and sharp edges are removed from the blocks. This is an important step, ensuring that the block will hold up at higher power levels. Some of the deburr work is to remove sharp edges to aid in assembly work, while other deburring is done to remove sharp edges that cause stress risers and potential wek points.
Powerstorm pistons are designed exclusively by Livernois and only available through Livernois Motorsports. Each design is developed to match the specific needs and requirements of the engine and application. Where as most companies just use "off the shelf" pistons, Livernois know's that in order to achieve maximum performance and reliability that you can't just settle for off the shelf parts. Taking from over a decade of building winning race engines, alongside the extensive time spent working with OEMs on development, Livernois designs each piston to be a perfect fit for the application. Features like increased ringland thickness, increased skirt thickness, added struts and bracing, revised ringland stack, custom skirt profile, and many other things, all go into making a Powerstorm piston the best piston on the market.
Powerstorm connecting rods and designs have become the industry standard design for many different engine families.
