new bellhousing vs. older bellhousing

[murdoc]

are the later model aluminum bell housings interchangeable with the heavy cast iron bell housings of the our year trucks? I want to go with the aluminum ones because 1: they are lighter weight 2: all four tranny bolts are on the outside, making transmission swapping way easier.

i have 66 c-10 with the factory automatic that im converting to a three speed overdrive. bell housing to end of tranny is almost exactly the same length as the powerglide i have in here so i wanna use the automatic cross member for that and not have to deal with my e brake system

Check where your starter is bolted to. If its to the tranny then no. If its to the engine then yes

I threw one out of a muncie on mine. With the muncie ofcourse as well, but yeah, it bolted up.

Yes the later aluminum ones will bolt up to the block. Since your truck is an original auto, your starter should be bolted to the block, so that shouldn't be an issue. As long as the 3spd trans you're using has the provisions for a trans mount at the rear, you should be good to go.

The newer pickup aluminum bellhousings have a bigger center hole than the old cast iron ones. The car 11 inch alum ones will fit your clutch and the center hole is the same size as the cast iron.
