Well, the Street Rod Nationals North at Kalamazoo was great. I met Tom Langdon from Stovebolt Engineering, and he had quite the swap booth set up. Tom came over to see my car and of course, gave me some valuble pointers on "tweaking" my inline. I also met several Inliners and we checked out each others rides. The milage on my '40 was very good. I averaged 18-20 mpg @65mph! The day of cruising on the Fairgrounds I only got 11 mpg but that's because of all the "Rapping" going on. The cars that had inline motors got a lot of attention over the "cookie-cutter" 350 small blocks.
Tom Langdon's best tip was to check your idle jets on your carbs. On the Holley/Webers I have, they are very accessable(as Tom Showed me) and they can be in the wrong position. I had 50's in the primary and need to check if the secondary is smaller. If so then swap em. Tom said that you should experiment by going down to a 45 then a 40 to see how your motor reacts. He has 40's in his and said he gets 22-25 mpg. I'll get back to the B-board on my findings.
