Holy Cow, in one clip of the engine on a dyno they show it reving up to 6 or 7000 RPM! Ahh, the joys in the life of an automotive test engineer!

Here are two photos from the test run, and one from about a year later. Somewhere, a long time ago, I had heard that the test car had a stick shift and overdrive. Never have seen any photos of the interior, and do not know the serial number (which would have started with 5582-1xx, the prototypes had only a three-digit suffix).

At the very beginning of the video, the engine being lowered into the car has a flywheel; obviously a standard transmission.

From experience, anything more than 5,500 RPM is usually fatal to the Packard V8. The production valve spring retainers were too soft and the inertia of the long, heavy valves would pull the keepers through the retainer and drop the valve into the cylinder. Every standard transmission Studebaker Golden Hawk engine we've ever opened shows evidence of this having happened. Toward the end of production, hardened retainers were fitted.

Thanks for posting this! The quality of the film is amazing, guess because it was "remastered".

Same channel has a number of Packard videos, here is the playlist link: Packard Playlist

Also a video on the 1957 Packard Introduction & Studebaker-Packard Press Conference, which I didn't see on the playlist. Unfortunately the quality is no where as good as the V8 Durability Run video. Here is the link: "57 Packard Introduction
