AKIQPilot Posted July 3, 2018 Share Posted July 3, 2018 Interesting. I've never seen that model before. I did a little research and I can't find anything that looks like that. If I were to guess I would say a 1975 440 FA of some sort. Someone over on the DooTalk vintage page could probably tell us what that is.

It’s definately some kinda 440 free air but I’ve never seen that hood before Quote Link to comment Share on other sites More sharing options...
AKIQPilot Posted July 3, 2018 Share Posted July 3, 2018 This is a '77 TNT 440. The hood looks similar to the one you posted. Same seat and tunnel graphics. That one above may have been some sort of factory racer or custom hood. Quote Link to comment Share on other sites More sharing options...
Rod Posted July 3, 2018 Author Share Posted July 3, 2018 Maybe a TNT with the hood cut or scoop removed? Quote Link to comment Share on other sites More sharing options...
AKIQPilot Posted July 3, 2018 Share Posted July 3, 2018 Yep. Scoop removed and some fiberglass added to direct air directly to the cylinders and keep snow out of the clutches and pipe. Quote Link to comment Share on other sites More sharing options...

It's impossible to tell by looking at the top of the cylinder heads. 340 and 440 have the same bolt pattern. Quote Link to comment Share on other sites More sharing options...
DriftBusta Posted July 3, 2018 Share Posted July 3, 2018 Prolly has a colony of mice living in every orifice of that old girl. That hood style doesn't look familiar at all to me, but free air tells me she was once in a pretty aggressive state of tune. Old man back in the day went from a 72 tnt 640 to a 73 TNT FA400, that was so much lighter faster better it wasn't even funny, revolutionary machine for ski doo. This is my uncle rednecking it down the side of the road on his 74 fa. Old boy is in his 80s now and still helps my cousin with his asphalt racer vmax4. 1 Quote Link to comment Share on other sites More sharing options...

The hood style is definitely from a '77 TNT F/A. Modified of course but thats what year sled it is. I have a '73 TNT F/A 400. It's incredible how light and fast these sleds are. The Factory Blizzard versions were even more impressive. Pistons for the 400 sure are hard to find.
