I just got through putting one back in my 54. It difficult but can be done. I bought the v-8 crossmember and purchased some 230/250 motor mounts from NAPA, turned them upside down did some grinding and cutting here and there and it worked out fine. The throttle linkage was a major issue. I modified the v-8 thottle linkage from chevy duty for this.
One question though: Why would you want to do this?? I don't believe you will get a noticable performance improvement out of the 250. If you can go find a full pressure 235, an easy drop in. In my case the 250 is all I had and it had just been rebuilt when I purchased the truck. The PO really messed up the installation so I had to re-do it.
As far as the transmission mount, I put the Muncie 22 four speed back in the truck with the Chevy duty transmission mount.
Let me know if you still want the pictures
