I was just looking on Ebay at Franklin parts and came across a 12 cylinder Franklin for sale. I had seen drawings of the 12 cylinder, but I didnt know that they actually produced any. It appears to have double turbo chargers. It just goes to show how inovative the Franklin engine company was. I just thought other Franklin lovers would enjoy looking at it. Only 2 days to go on the auction. I wonder about a 337 into my Cruisair? (oops, I must return to sanity) _____Grant.
