I wish I could be of more help to you, but I'll give you all I can on it. In the very late '50's or very early '60's, I had a long conversation with Barney Navarro. Barney was one of the pioneers at the lakes and in drag racing. At the time, Barney was absolutely bonkers about nitrous oxide. I had never heard of it before and he sounded like a missionary. Barney had a lot of miles under his belt at the time and to be honest, he was almost scary about it. He showed me a roadster he had with a 3/8 X 3/8 flathead and a nitrous system installed. I don't remember a damn thing about it except that there was strange copper tubing on it.

Barney had a shop on San Fernando Road, either in Glendale, CA or L.A. He manufactured speed equipment for flatheads. I would suggest that you contact Vic Edelbrock Jr. or Ed Iskendarian (If he's still alive) about it. I'm sure Vic Jr. was involved in his dad's company at the time. All those guys that were producing equipment knew each other and one of them might actually remember something about it. They were all very competative and I'm sure they all kept up with whatever each of them were playing with. It's also possible that Barney had kids that might know something about it.

I wish I had paid more attention to it but try to understand what it was like to have a guy telling you that laughing gas made a car run like it was on Nitro. If I were to make a guess, I would say it was probably injected into an air cleaner.
