1974 Pontiac Lemans Front View
Fred Bitner operated the Hoffman Machine/Stuska dyno during our test session. We made a few part-throttle warm-up runs and then let it rip for a full power pull. On 92-octane pump gas, the engine made 483.7 hp with the Holley carburetor.
Dyno Results
Each pull was backed up by another to verify the results.
