Jack,
What's an "air gap intake?"
BTW Kettering is a great look-up. Seems he invented about a million things (well 300 or so patents). I wonder if he worked on the Cadillac 331, too. Since they came out the same model year, were they parallel projects, or was on really based on the other?
Look up Kettering here:
http://en.wikipedia.org/wiki/Charles_F._Kettering Couldn't find much history on the Caddy.
Besides wide-spaced bores and plenty of room to grow, what was the most outstanding (even if not ground-breaking) feature of the Packard V8?
I've got the complete "white paper" engineering report on the 352c.i. Packard V8, and some of the reasoning behind their design decisions, but can't point to one that is unique. However, it did mention that the much vilified vacuum pump was also meant to scavenge air from the crankcase at idle to provide ventilation when the car was not moving (thus no "draft" being created for the draft tube).
