Hi All

I have an important question. I am in the process of returning my 60 Burb back to a 3-on the tree. Many years ago my older brother blew up the original drag racing his girlfriend in reverse...( don't ask ) .. We had replaced the blown 3-speed with a 4-speed work truck tranny with a low granny gear.

I long while back I had obtained a good 3 speed from a member who was putting in a 350 with auto. Below are the two different bell housings that have different bolt holes although they both work/fit.

Is the first one with the little cover on the rear top the correct one for the 60 Burb 3-speed ?

It has been a hassle finding the correct clutch and parts, but looking forward to making it back to original .

The bottom one looks like the 305 V6 one (not an expert) TJ might chime in. The first one looks like a I-6 bell?

The top one is what came with the 3-speed, but I do not recall what engine the person had that he pulled out.

The bottom one could very well be the original from my Burb and we might have just installed the 4-speed with that bell housing.. I just can not recall since it was around 1979ish when wee did the tranny swap.

I definitely want to be as original as possible..

What do you mean when you say they both fit? Do you mean the trans will bolt to either one? The engine bolt pattern is different and I am fairly confident the top is for a 235 (later model I6 use std small block bolt pattern) and the bottom is used with the V6.

The motor is on a motor stand and we had not tried to line it up but it looked like it would bolt on to the block. It just looked like the larger one had two extra bolt holes.

We just didn't want to drop the engine off the stand and needed to get the correct bell housing cleaned and painted.

Is the smaller one any of value to others ? or do most of them get trashed for larger motor change outs ?
