3/4 or 1 ton with 4bt
Hi all I was wondering if anyone was aware of someone who's done this: put a 4bt in 3/4 or 1 ton truck. So, if I have a 88-94 f250 extended cab would a 4bt be enough to power it? If I can gain 5mpg and lose 5000lb towing capacity vs a 12v, than it's worth it to me. I don't see myself towing huge amounts of stuff, maybe a camper or a car hauler occasionally.
I've recently given up aspirations of importing an early 90s diesel land cruiser, it's just too damn expensive. so the idea is to make a vehicle platform with what I have available in the USA. I want select-able 4x4, leaf sprung FF axles, and the ability to run WVO. I like the cummins because of timing gears - sleeved pistons would be nice but I guess you can't have everything.
I'm very partial to the late 80s early 90s F series, as it was the last of the big 3 to provide leaf sprung front axles. The 4 doors are too long for me, so the hypothetical recipient would be a F250 with an axle swap out of a 350.
Transmission is still up in the air. Would the zf5 be good candidate or would I need to use a GM transmission? I've heard a lot of horror stories about the e4od, and have seen people hook up the GM 700r4 to the 4bt. I'm not 100% sold on autos, i prefer simplicity and ability to start without electricity that comes with a stick but that torque converter is nice for crawling and towing.

6BT is cheaper/easier in the end. Get the whole 'kit' from one Dodge truck. Intercooled or not isn't a big deal. Getrag works fine. VE pump will get you the best economy.
Adapting a ZF should be OK so long as its a 460 or diesel version. The other patterns don't work. Would not bother converting to a cummins and pairing with an auto... but maybe a 47RH if I absolutely had to have auto.
