Naaaa - I wuz only being thought of in '61 - came along a couple of years later. That's wild about the Tempest - I'll have to keep and eye out at shows / auctions for one of those just to have a look at it.
Hope Mike finds his problem - maybe Gaffney1951 (Mike) would have an idea? - sounds like he's pretty familiar with non stock running gear set-ups. Think he built a Galaxie and believe his Tbird has a C6? I'll ping him and get him to take a look at this thread.
