Well I retreived the rest of my junk today, and talked to Gary Schaedler, a machinist who worked for Barney then, and did welding and fab on this motor and the car. I may interview him later (he assented), maybe I could wangle a talk with Barney hisseff. I should talk to some journalist type for hints 'aforehand.
What I have is motor #1, motor #2 is the indy motor. #1 sustained some damage on the test track (the damage looks like 30,000 wear to me, but at 3.5 hp/cuin any wear could be fatal) and it got set aside. There is a #3, or parts thereof, that Barney has so far kept.
These were the only Rambler motors Navarro ever made according to Gary.
It couldn't be a better arrangement. Except for connecting rods -- and I may be able to get those from their current owner -- I have a complete monster motor kit with terrifying historic overtones.
I don't precisely know what to do with it, to be honest. Massive HP isn't my game, but maybe I could make an exception. Clearly I'm not going to even blink even in the direction of the exalted numbers Navarro got -- 3.5 hp/ci!, but it would seem that with this massive O-ringed, 7000rpm block I could slop out less than half that with little effort.
I did a whole new set of photos, in daylight, of some of the major components, and pulled numbers from what I could find. I'll do measurements etc as I go. There's a bunch of text on the new page also, including the partial story of this motor from Schaedler.
