The Powerstorm Street Series product line is built for customers with budget and value as a top priority. These products are built using the same standards and quality as any Livernois product but with parts and service options more geared around value. These products utilize components that are targeted at the specific application they are intended and are not meant as one size fits all product line. In most cases the applications for the Street Series product line are street oriented vehicles that are not heavily modified and see infrequent track time. The Livernois Street Series line of products are designed with specific goals and targets in mind when it comes to power and durability. By adhering to specific design goals for the products Livernois is able to produce a high quality product that meets a very specific requirement for both power capabilities and durability while still being affordable for the budget minded performance enthusiast.

Street Series Details & Specifics

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. 


Pistons

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 Powerstrom piston the best piston on the market. 


Rods

Powerstorm connecting rods and designs have become the industry standard design for many different engine families. From our H-beam design, to our higher end I-beam offerings, these rods are designed to handle the increased horsepower and torque of a modified performance engine. With standard features like ARP2000 upgraded bolts and precision tolerances of just .0001, these rods are the best available. 


Crankshaft

Each crankshaft is precision balanced, and treated to a variety of treatments in order to ensure the best possible performance and durability.
