“The L8T platform is an engine builder’s dream,” say Fluidampr project lead, Nick Orefice.  “It was originally developed for high-torque towing capacity in GM’s Heavy-Duty truck line.  However, the robustness of the cast-iron block with nodular iron main caps and a forged steel crankshaft promises lots of potential for engine swaps and crate programs.”

Upgrading to a Fluidampr performance damper when engine mods are done further ensures long term durability and optimum power by controlling crankshaft torsional vibration.  In addition, a custom mandrel to power racing parts, such as a dry-sump, can easily be installed by using the damper’s pre-drilled and tapped 3.2” bolt circle pattern.
