I've got a '49 4400 with the old 216, currently down to the frame. A friend wants to make me a deal on a 7.3 Diesel out of a '92 International 4600. Before I give it any serious consideration, I'd like to have some idea of what I would be getting myself into. Has anybody tackled this before? I just can't see it going in smoothly.
This was my Grandfathers old grain hauler. I like the idea of staying original for now, but had thoughts of going modern with it in the future. Is this Opportunity knocking, or a disaster in the making?
There is so much difference in the weight and output of the two engines that I think you will end up having to re-engineer a lot of the truck to handle the greater power/torque and the temptation to use the power to drive faster with larger loads. Axles, transmission, engine mounts (frame too?), cooling system, and brakes (maybe steering too due to weight increase). It might be safer and simpler to start with a complete modern chassis and work to mount the older cab on it.
I have a 93 Ford farm truck with the same 7.3 engine. It has loads of bottom end torque (compared to a 235). Top end is not so good as without a turbo she steadily loses speed climbing grades and spews black smoke. On the plus side, the electricals and mechanicals are very basic (1950's technology) and once dialed in it should run for a long time with little upkeep. Rebuilt fuel injector pumps may be in scarce supply in the future as they are not abundant now. As others stated, the heavy weight of a 7.3 may be of issue.
I think I'm gonna stick with the plan and just keep it original (or close to it) for now. I've had the truck for several years, and I'm just now to a point where I'm making some real progress. As much as I would like to perk it up, job one remains getting it back on the road.
I appreciate the input. Helped confirm my gut decision, and put that feeling of temptation to sleep.
We put a 37 Chevy cab on a UD diesel chassis with a roll back bed. Gets lots of attention but was MUCH work so I think you are making the right choice. Maybe a full pressure 235 or 261 upgrade?
Yep...worked on them lots and as long as they stay in a ford or international....never in anything else. If you want diesel go first or 2nd Gen Dodge cummins.but still lots of work.
