I have a turbo 400 that says gm on the oil pan, is about 34 inches long and is out of some thing from about a 70 to when ever they quit making them. I know it's not a Chevy 400. It has a 'dip' on the top between the 2 top bolt holes. A friend of mine wants to know if it will replace a turbo 350 on a 350 engine in a 1981 Cutless or Buick mid size car. Anyone know? Thanks

It will, but it is about an inch longer. It will require moving the crossmember back and the yoke is a different size. Your driveshaft will need to be shortened 5/8".

I appreciate the reply.
