OK, so the '86 is in the shop waiting for a diagnosis. The damn body is so rusty it has me thinking, "should I swap the plow hardware out to a different truck"?
Here is the question. What are your opinions (all thoughts welcome) on getting a regular cab/long box with a manual (4 or 5 speed) and either a 4.9 or 5.0; or a supercab/short box with a auto and a 5.8 to have behind a 7.5' snow plow?
I am thinking the manual is better? 4.9 better for plowing than a V8 (torque)?
I found a couple options on Craigslist and local ad boards, and am wondering if I should put a bunch more money in a rust bucket (can see through floor boards) but end up with a known quantity. Or get a less rusty, better running truck, but have to transfer the plow and perhaps run through some of the same issues again.
A 4.9 with a 5-speed would probably be a good choice for you. A 351 is also nice, but it eats more fuel. The 4.9 will have plenty enough torque, and it will burn the least gas while plowing and while sitting keeping yourself warm. Plus the 4.9 is known to be very reliable into high miles. I wouldn't go with a 5.0 if I were you because it lacks low end torque, and will burn slightly more fuel than a 4.9 I6.
Regular cab and long box, or super cab and short box is a person preference decision. Of those two, I prefer regular cab and long box because I like the bed space, and a regular cab gets nice and toasty in the winter with less space to heat (& lose heat).
A contractor friend used F250s with the 4.9/C6. He claimed that was the best gas set up for plowing parking lots. All 5 trucks still had the originial transmissions and engines after 150k and were retired for rust issues. While I usually prefer a manual it could be a real pain if your doing a lot of backing or some one else is driving the truck. In my limited experiance plowing, U joints tend to fail more often on manual plow trucks.

one thing i would speculate about a manual is you would have less tendency to shift the trans while you are moving, and usually with a plow if you clutch in the resistance from snow stops you fairly quick. it seems around here (and i have done it myself a few times) people are shifting while they are moving, which is bad for transmissions, and most people seem to do it on automatics more than manuals, so that is a food for thought
another thing, if you got one with a 4 speed with that granny low first, that would be a real snow mover. also i would get one that is pre airbag, so you dont hit a bank too hard and set the bag off. otherwise the 5 speed in 4 low would be about the same as the 4 speed in 1st
Auto transmission all the way. I've done quite a bit of plowing (residences, roads, parking lots, etc) with both autos and manuals, and the auto is definitely the way to go. For a 7.5' plow, engine size won't matter. Find a 250 if you can, any good welder can switch the old plow over to the new truck, and a 3/4 ton handles the weight much better.
While the 4.9 FEELS torque-y, someone once posted factory dyno results from the 4.9 and 5.0. The 5.0 had more torque at every speed throughout the torque curve.
But that's irrelevant anyway when it comes to plowing snow. You'll lose traction and spin tires before you run out of power to push a pile of snow. Shifting an automatic is enough of a pain the rear--I sure wouldn't want to work a clutch, too. You just have to discipline yourself to come to a complete stop before you shift the auto tranny.

i would like to see this, as i would like to know what the 5.0 is making for torque at 1000, 1500 and 2000 rpm and how long it holds its peak torque vs the 4.9, remember the 4.9 has more of a torque line, not a torque curve, not saying anyone is wrong just saying i would like to see the numbers,i as i know, by owning one and driving a family vehicle with the other (other being the 5.0) and towing with them both, which one gets better gas mileage and which one tows better. i will say this, when a 5.0 has to shift to second gear at 50 mph going up a slight grade and the 4.9 towing a load with in 1000 pounds of the load the 5.0 pulled only had to shift out of overdrive and maintained speed, i dont care how much more power the 5.0 has cause it will never tow like a 4.9, the family truck has a snow plow on it (its either a 8 or 7.5 foot one, its been awhile since it was bought) and it takes 4 low and first gear just to get any power out of it while plowing within the recommended plow speed in the ford manual,
I agree with these guys on the fact that life would be much easier plowing with an automatic. I'd go for a truck with a C6 if I were you.
Also, you shouldn't have too much issue switching the plow over. The trucks are similar.
And as these guys have said, you would be better off with an F250 because it'll handle the plow weight better. Plus you get to sit a couple inches higher, haha
Just keep in mind. the 80-91 plow frame is one design, 92-96 is another
Also the f150 frame is not the same as a f250/350. I have a Meyer's poly plow on my 90 Bronco with a 5.0 and a 5 spd. It plows nice for me as I use the low gears when plowing. Not very concerned about how fast I plow the snow so with 2nd gear low it does a marvelous job. I did add F250 front springs to my bronco to help with the extra weight. If you go with a steel blade you need to start with a F250 or an f150 with the f250 springs...

Thanks! I do have Timbrens in the front of the '86 now and that helps a lot. It also has airbags on the front (from previous owner) but they leak down over a week or two. If you pump up the airbags, the 'bags and the Timbrens carry the weight pretty good. Hardly sags when you lift the blade...
Right now the '86 is a 4 speed/5.0 and it seems to work OK for our plowing. L seems too low and 2nd (1st?) a little too high. Thinking a 5 speed might have a better combo.
We have about 1/2 mile of private road to clean out, plus our drive and the neighbors drive. It is a pain to shift, but most of the time is spent going forward along the road. It is not like doing parking lots (I have done plenty of those with different trucks). Our road plowing is pretty easy...
Good to know about the 250 frame being different. I suspected as much. Probably will stick to a 150.
