Author Topic:   early saginaw 3 speeds....
posted March 28, 2003 08:29 PM
has anybody ever ran saginaw 3 speeds in their cars that were out of 55-57 chevys (possibly other cars)? i know they had 2 styles..a short tailshaft and long tailshaft. i was told that the long tailshaft tranny is the same length as a regular saginaw 3 speed. i would just need a different slip yolk. i know these trannys are about 40lbs lighter than a normal 3 speed saginaw but i dont know how well it would hold up. thanks for any info.

I have seen several guys around here run them and they never seen to have many problems with theirs. I would have a spare in case something would break.

I am switching to the same tranny this year for oour street stock. The modifieds have run them for years. I would run the long tranny and make sure you run the heavier input shaft. Most of the input shafts are stepped down after the splines. You can run them but they are not very strong. I would also have it rebuilt. If you do all of this you shouldn't have any problems and you will lose both rotating weight and static weight.

I know of a couple racers runnin the "potbelly" Saginaw in this area. Use the one with the bigger input shaft, tho. I believe these were in production until the late 60's. Get a backup & good luck!
