the motors on the 64-65 773s were considered the least well made of the series of Hudson motors. Compared, for example, with the 1950s. I have read that they were made in Japan and not especially well.
The original 773 (1950) motor was an application of the 622 switcher motor, which means it was never really designed for the situation. Toss in weight and mediocre manufacturing and you get - - - slow.
For $50 and a rectifier, a Timko motor will make your 773 into a ton of fun!
