4speed diff. between 318 vs 383?

[megaivtes]

So a deal I was looking at for a 66 satellite big block seems to not be happening. I’m going to look at another 66 satellite with 318 and 4speed.

Is the 4 speed the same between 318 vs 383?
As far as I can tell, it’s a straight swap from the 318 to the big block, using the same 4 speed.

The bell will be different and possibly the drive shaft length, but both should be a 23 spline unit and a straight swap, to my knowledge.

Different bell and flywheel.Shifter might just fit where it is.

There could be a difference if the 833 is an overdrive trans. In that case, the input bearing retainer diameter may not fit your bell house...............................MO
