The GM 8.1L configuration Reviva offers is tailored to Workhorse chassis step van applications including parcel package, snack food, bread, and uniform/laundry delivery vehicles.

Reviva uses OEM or equivalent pistons, rings, bearings, valves, gaskets and other components, making sure this engine will stand the test of time. The engine is dyno tested with the OEM GM ECM, specific to application, not the generic or modified to “get it close.”

All Reviva engines are assembled in the USA.

REVIVA’S DYNO TEST

All of Reviva’s Complete Drop-In engines are 100% dyno tested prior to shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm up cycle; three separate cruise segments simulating light, medium, and heavy throttle conditions; maximum torque and horsepower tests; and a black light leak detection test with dyed oil, coolant, and fuel.
