1991 Ford IDI engines/trucks for towing

In the scheme of things, pricing for an older MDT will be on par with a pickup. A 90s Navistar/international 4700 should be less than $10k. The 4600 model has the IDI 7.3 in it. If you can find one with the spicer 7 sp manual, would be best trans behind that motor.

Depending on what you are using the truck for, you might qualify for a farm/agriculture exemption from some CDL and DOT rules. Otherwise you're looking at a class A CDL if your combined weight rating exceeds 26K and your trailer GVWR exceeds 10K. Your state's DOT website should have the details.

<26,001 GVWR and hydraulic brakes, the driver's license requirements are the same as a pickup unless you are engaging in commercial activity.

OP, why are you so in love with a pickup? For the money you are talking a older class 6-7 pull your load, and any repairs would need done once, then never wear out again.

Hello! I am not sure I speak the language :) - what is an older class 6-7?

Say a F-750 Ford. International makes medium duty trucks by millions. Freightliner, Mack, Pete are also players on the board.

I had a 1991 with the 7.5 gasser. As I recall the diesel was only rated for 14,000lbs GCWR. Since the truck that you are talking about weighs over 6,000lbs its trailer tow rating is less than 8,000lbs. Having said that, I have seen people pull much much more than that and get away with it. The other other question is How much do you want to pull up a hill with only 150hp? I remember driving a friends F350 1992 diesel and it didn't have much get up and go without a trailer.

Yeah, you hook 12klbs to it and try to pull a hill, you may need to chalk the tires or paint some lines across the road to actually see it moving!

Back in the day, when I would pull out of the quarry grossing near 110,000 with 427 GMC, it was said needed to drive a stake in the ground to see me moving up the hill, but when started down, it took a running automobile to get around me. (Once went past a bear at the bottom. In the mirror could see him, looking at me, then his hat, deciding which to chase first. He caught both)

Fish,

Nice touche on Grit.....

For OPs use frankly. The IDI 7.3 us as noted by many for freeway work. BUT like myself, I doubt the OP is going to be pulling the loads he's talking about down the freeway. Speeds are slow ie under 10-15 mph pulling tailer out of the field. Very little to no additional air cooking due to speed. A lot of sailboats, off road heavy equipment, using a turbo is a disadvantage vs a non turbo with equal power specs.
I'm wondering if putting yes a rebuilt motor, it better yet, a T444e block with the mechanical injection pump turned up, open up if possible air intake, this should net this motor from 185/385ish another 20-30 hp, I'll swag upwards of 50-75 lb ft of torque. Depending on trans, dumping 433 or 488s I'm pumpkins, yes lose freeway ability. Or leave as us with probably 4.10s. know he will use 4lo getting out of fields in softer spongy soils etc.
This latter option maybe the best better option. I'm doing a too bad there is not a non turbo option for current models for this use. With lower gears in axles. Or a detuned 300/600 lower psi turbo option. The one size fits all that manufactures are going with today, does not work for everyone.

Hahaha, touche!
I was waiting for someone to say that!
I have towed the boat with it a couple times last summer. Now it's in 1000 pieces in the shop, almost ready for paint.

Looking forward to the pics when its all done. I'm sure it's a fun project for you and your son.
