Well if you are really looking for a Salt Fat Car, that narrows in down to Hudson's, and the only two I know of are Tubby Racing from Eugene, Oregon which I believe still holds a class record with a Ford Flathead. The other would be Steve Kahn (sp ?) from Astoria, Or. or Longview, Wa. (has lived in both).
Now if you decide that you are open to non Salt Fat Cars, I would sugest you visit this sites For Sale section, Subscribe to Bonneville Racing News, Join the SCTA so as to recieve their monthly (?) magazine, watch Ebay, or last but not least visit RacingJunk.com and search under Land Speed Racing.
Welcome to our site, and I am afraid that you will have to put up with sarcasm from a select few idiots which include me. Bob
