Thanks for the help.
Without actually measuring a 1965 cab, I can only say that I think it can be done.

I do know with 100% certainty that a 12V fits nicely into a 1979 F-series engine bay with ZERO firewall modifications and no body lift. There is ample clearance between the Cummins fan and the Ford radiator as well. The only significant modifications are to the core support and the frame. The core support modification was the cutting of two 4"dia holes for the intercooler connections to pass through. An earlier non-intercooled 12V engine would not require these holes. The 4WD frame needed one modification - the removal of the top half of the frontmost crossmember to clear the Cummins (rear sump) oil pan.

Take your time fitting it all in and measuring (or mocking up) as much as you can before fabricating the engine mounts. Measure twice and cut once is my motto.

My build thread on the FTE site has been updated intermittently, but feel free to PM me should you have any specific questions. I like 1964/5/6 trucks as well, you can see a dark gray primered 1965 F750 (another rebuild project) in the background of some of my build thread pics...

1979 F250 Rebuild / Cummins conversion - Ford Truck Enthusiasts Forums

Since your truck is a 1965, and a 2WD, it should have twin I-beam front suspension. The front frame crossmember is pretty wide to go over the I-beams, so a typical Cummins oil pan won't work. Front sump is still too far back... Rear sump is out of the question as the tie rods are back there. I do not like the idea of swapping I-beams from side to side and running the steering linkage out front, as that throws the ackerman principle out the window... I did some quick comparison measurements on a 70's F-series 2WD truck, and I think it can fit with a custom oil pan. The sump needs to be much shallower to clear the crossmember, and longer to maintain capacity. Adding a baffle I think is a good idea. My next two conversion projects will be a 74 F350 and then my 69F100, both 2wd trucks.

it would be great to start a group for these models of Fords. I'm still in the progress of building my 79 supercab dually 4x4 with a 96 p pump motor. I plan to have it road worthy not done aound the end of october. I rreally enjoy readin the post of the ford conversions and it has definately helped me with ideas on my build. My son is building a 90 model crew with a cummins. I guess it runs in the family.
