I am looking into putting a cat 3208 and fuller roadranger 10 speed into a 74 f250 4x4. I am looking for any advise for the build. I picked this engine because I have had good luck with these engines and I have many to swap out if needed.

 

We did a few Detroit/ Perkins swaps into mid 70's F250's back in the late 70's. Both OE manual, and Alison auto.
