at the 1:45 mark, you can see the Packards (Not 7th series) on the proving ground track hitting 100+mph. Scary!!

Here is more on the film. It is a 7-45 sedan being run thru the "standard car report sheet" events that require a total of ten thousand miles in no more than ten days. Film did day this one was completed in less than ten days. Also, there were several events, dragging a dynamometer car, hill climbs and stops, rough track unpaved road and acceleration tests that were part of the ten thousand miles. Of course it is stated test car is one pulled from the line and not a special car. It and the tests truly appeared to be a standard thing. As for babbitt, I drove my 26 Model T from Knoxville to Richmond VA and back (on secondary roads) for the 100 year celebration and have not had to pull shims from the rods or crank yet after another national tour last summer. I am not ready to put the Packard out on the interstate but do believe good poured bearings with high grade oil are quite durable.

The Seventh Series 734 Speedster customers had the choice of two gear ratios 3.33:1 and 4.61:1.
The other models in the Seventh Series customers had the choice of three gear ratios 4.07:1, 4.38:1 and 4.69:1. Johm F. Shireman

"but do believe good poured bearings with high grade oil are quite durable."
Ok. True. But what kind of longevity do u expect to get from the engine in general??? I.E. is it unreasonable to say that nearly all engines prior to ca. 1955 (except maybe Hudson) required major overhal at 40K miles???? SO it becomes a personal judgement call. If u only drive 500 miles a year 25 mph in parades and soforth then the 40k mile longevity is just fine. It would take 80 years to wear it out. But run 5k miles per year and a rebuild is in order every 8 years. BIG DIFFERENCE!!! So even if we erroneously assume the babbit to be as good as inserts then the cost of rebuilding with insert conversion would most likely be recouped in 16 years NOT TO MENTION the ease of replacing the inserts IN-CAR if necessary. SO, the babbit vs inserts is quickly becoming a 6 volt vs 12 volt type argument. It depends on individual owner demand.

Keep in mind Keith that a lot of people aren't like you and I and don't drive their cars as often as we do and I did/will again. I plan on using my cars as daily drivers and are building them as such. I would have to say that most, probably 90% or so, of original antique car owners don't drive their cars on a daily basis. For these people, 6V and insert bearings are fine. If I had a car that was mostly driven on nice days and rarely seen over 1000 miles a year that's how I'd leave it. If I'm driving it all the time, it better be up to the challenge.
