Ok, that helps alot. So this is pretty much standard Chevy garden variety fare, which should bolt to most bellhousings and clutch assemblies, right?
I just needed this to be a basic 3 speed, and the non syncro low isn't a problem.
All the info you guys have given is really appreciated.

Yup, and thanks to good 'ol Chevy interchangeability, any of the "traditional" GM trans will interchange. Saginaw, BW, Muncie, 3 and 4 speeds have the same mount locations, bellhousing pattern, and I think tailshaft length. Input shaft splines should be the same to at 1 1/8" X10, except some of the four speeds have 26 splines.

Great. The trans looks really good, and the price was right. I'll pull the side cover when I get to that point in the build and make sure the gears look ok, but a quick spin through the gears last night seemed like it was usable.
I will count the teeth on the marine flywheel that is on there now, that should give me some idea of how many I will need on a regular stick flywheel.
Only thing I am still a little confused on is the external/ internal balance thing.
Thanks again, Don
>Only thing I am still a little confused on is the external/ internal balance thing.
The balance thing was touched on, but I'll try to help. Before the one piece rear seal on small blocks, the 350 used a zero balance flywheel as the engine was internally balanced. Look at the crank flywheel flange on a pre-'86 350 and you'll see it's not round, but has an eccentric shape that was part of the rotating mass used in balancing. When they went to a one piece seal, the crank flange had to be round so the seal could slip over it. As a result, the eccentric mass that was on the flange of the old crank was transfered to the flywheel, thus the engine became externally balanced. So, you need a flywheel for the one piece seal crank. The earlier flywheel won't fit anyway.

Now I got it. I'm just a little thick sometimes. Boy, this Chevy stuff is hard. Think I'll start building something easy, like maybe Hemis.:rolleyes: :rolleyes: :rolleyes:
Anyway guys, thanks for all of the good info you posted for me. I think I have the situation down now. I had some concerns about the trans, because it looks so small and all that I thought it might be some oddball from like a 4 cylinder or something.
Hope I can return the favor sometime.

The number is 3743368, and it's a 58-63 Saganaw three speed. That particular number is the case part number. They came in a six cylinder, and wide and close ratio for V-8s. It looks like the six cylinder input shaft has a different spline than the V-8.

Classic Muscle could probably help when you start to buy the clutch and flywheel.

Another very good piece of the Chevy puzzle. I am going to have to pull the front off and see if the shaft is a 6 cyl or not.
Thanks,
Don
