-  Performance Thermostat

Livernois Motorsports & Engineering incorporates this high performance, low temperature thermostat to reduce the operating temperatures in your performance engine. This will allow for the engine to naturally make more power power, ensure consistent performance, and increase coolant flow to help extend engine component longevity.


-Livernois Motorsports CNC-Ported Cylinder Heads

Developed completely in house, our cylinder head experts design the ports and then test them on airflow testing department, from there they head off for further testing on dyno to verify the results. In combination with the increased flow, the heads are then outfitted with Livernois own proprietary custom components. Custom springs, retainers, and hardware are used to create a cylinder head combination that's built for ultimate performance and durability. 


-Livernois Motorsports Pushrods

One critical item when upgrading a camshaft in any engine is using a proper length, and strength pushrod. Our Pushrods are made from 1-piece .080 wall Chrome Moly right here in Michigan, ensuring the best durability, and consistency.


-Livernois Motorsports Injectors

Due to the impressive increase in power and performance from the items in this upgrade offering, it does exceed the limitations of the stock fuel injectors. To ensure proper fueling under all conditions, we have included our  Fuel Injectors. Nearly offering double the amount of fuel available over the stock units, they will aid in ensuring the reliability Livernois Motorsports is known for. 


-Livernois Motorsports  Camshaft

Camshaft profiles are built around Livernois Motorsports extensive racing background, as well as Livernois Motorsports engine development programs. This data and knowledge is what gives  camshafts the edge over their competitors, by utilizing the data from Livernois Motorsports engine development and it's special application requirements, along with our extensive racing background,  is able to design camshaft profiles that make more power, have better driveability, and produce a better overall engine combination then any other manufacturer.


-Livernois Motorsports Billet Rocker Arm Bases

Livernois Motorsports Billet LS rocker arms stands are available to help improve valvetrain and rocker arm control. With added spring pressures and larger camshafts the load imposed on the factory OE rocker stand and bolts often allows for flex and distortion. This translates into lost valve motion as the rocker arm deflects on the stand. These stands offer increased rigidity to keep rocker motion more true helping to prevent rocker shift at higher loads.
