Motor & tranny options

[MikeS.]

My 63 4x4 Burb currently has a 283 and a 4 on the floor tranny, not sure which model.

The 283 seems to be running well and the tranny seems to be also.

My dilema, I've always had a thing for a 350. I've rebuilt 2 in the past, long past but still... Also I'm getting to old and lazy to be double clutchin a manual.

So my ? to y'all is; What would I gain by swapin in a 350/th350 or newer tranny, what would I lose?

Would mpg be much different? What about T-case?

I think finding a newer 350 with an auto and a t-case might be the way to go. Possible a wrecked 4x4 Burb or p/u as donor. But then you have the whole computerized stuff too. I like simple carberated stuff.

Thoughts?

If it is built right, a 350 could get better mpg than the 283 as the 350 builds more torque, which is needed to move 4300 plus pounds. Unless it has been changed, your Burb will have a divorced transfer case, so you can put pretty much any 2wd trans in there. However if you can come up with a 350/th350 & transfer case combo, I would go with that. If you find one with EFI, and don't want that, it can be easily changed to a carb.
