What is involved as far as mounts and trans fit, headers etc. I think the 65 has the funky linkage set up and bolt on drive shaft flange but I'm not sure.

The shift linkage on 65 727's have accommodations for both lever and cable shift, you should compare the two when it's all on the ground together. The ball & trunion drive shaft requires special parts, you'll need to swap the output on the trans to the later style and possibly modify the drive shaft length to fit properly.

He should ditch the 65 727 and just build a newer BB 727. His existing linkage should then work back, and you have a better selection of convertors.

For that reason, the '65 transmission has value to someone who wants to keep the pushbuttons while getting rid of the ball and trunnion joint. In other words, don't throw it away! R.

If he has a 727 in it already and not a 904 he needs a big block 727 and a radiator. Other than that its pretty much a bolt in, may have to modify his engine harness to lengthen the coil power wire but thats about it. He will re-use the same driveshaft because he still has a 727. Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Don't get too excited on the trans... I'm sure the Imperial may have a two-piece driveshaft. They didn't have a slip style yoke, but a bolt on part that mounts with a nut on end of trans, that accepts a universal joint. You can use one to replace a B+T joint, and have a slip type driveshaft made. It uses the smaller size u-joint.

The 65 trans is still cable shift, even though they have column type shift lever. That's the issue, doesn't have slip style yoke.
