Haven't personally done it but researched it before I put a stock V-8 K in my '63 330.

I decided it wasn't worth the hassle for a street driven car.

Moves back approximately 1 5/8".

If you plan on using a crossram, firewall will need to be beat on or cut to provide room.

Rear transmission mount will need to be re-worked whereas you can get a later syle transmission to bolt up if you use the original style k with a Schumacher conversion mount.
