Hudson-
Glad to see this thread re-surface! This thread is where it all started for me, right after seeing a pic of Jim R's fladhead in the rides section. Jim's engine was the only one I found on the net at the time that was not stock, and had a bit of the "look" that I wanted for mine.
Here's Jim's engine:

When I bought my '50 plymouth, I had never seen a flathead six before, and mine looked more like an abandoned rusty old furnace that and engine.

The little pic of Jim's engine got me to searching the net for keywords like "Edmunds", etc. I started finding bits of info here and there, and then found this thread, which really got me consumed with flatheads. It's been a long road for my project due to lack of time, but it's just about ready for the BIG RACE. I hope to have the car on the road, er track, by June of '05. Of course, I've been saying that for four years now...LOL
Glad to see the pics of your race tractor, looks great. I'd love to hear a sound clip, I'm too far away for a visit...
