so for the driving I do in my truck I have been looking around and looking into getting a parts truck and adding 4wd to mine right now

or I was looking into getting a truck that already has 4wd but has a bad motor and pick it up for dirt cheap. I have an 82 f100 with a 302 that has 60cc heads and like it quite a bit.

I found this guy who said "I have a 95 Ford F-150 4x4 nice truck has 4 in lift and 33s needs motor asking 700 obo. " instead of just switching motors I really want to keep my truck. could I possibly change the whole underside of his truck and put it under mine? what problems could I run into if I were to swap everything underneath over other than i know it would be alot of work? Im working for my college over the summer and have plenty of time and a shop that I could use at my dispense so even if it took a month to swap it all i would be okay with it.

 

You have lots of options. If your truck and the 95 are the same wheelbase(both long beds, short beds, etc.) you could take the body and the bed off the 95, take the fuel tanks and the wiring off the frame, you may need to swap fuel lines also, and put your body on the 95 frame, put your tanks and fuel lines and wiring on the newer frame, and anything else you would need.

The only kicker is the transmission. You will need to use the 95 transmission since it's a 4x4 tranny. Hopefully the 95 has a 300 six, 302 or 351w. If it does, your engine will bolt right up to it. You could swap engines when the bodies are off. One other thing to look for: See if the 95 has a speedo cable. Ford went to a electronic speedo sometime around those years, so you might not have a place to hook the old mech speedo you have in your older body. You can get around this if you want to swap transfer cases, the speedo cable hooks to the transfer case.

You could keep your frame, swap the 95 frontend in place, swap the rearend in place(so the ratios match) and swap the tranny/transfer case in your truck. With any of these scenarios you will have to cut a hole in the flooboard for the 4x4 shifter(hopefully the 95 is not pushbutton 4x4). If the 95 is pushbutton 4x4, you could still buy another transfer case to get rid of that. I think they are around $150 from the junkyard.

 

My '95 was the electronic speedo (no cable). I think Ford switched to that quite a while before '95 actually.

And that brings up the biggest challenges, getting the wiring all happy. If the '95 is an automatic it's probably an E4OD which is controlled by the same computer that controls the engine. If you stick your non-computer controlled 302 in there you'll need to get a stand-alone controller for the trans. I'm not sure what would be involved in getting the '95 dash to talk to your '82 engine.

Swapping your sheetmetal onto the '95 chassis (assuming same wheelbase as Franklin2 pointed out) lets you keep the '82 cab wiring, so the dash issues go away. But there's still going to be a lot of wiring. Probably nothing too difficult, just a lot to do. And you'll still need to deal with the auto trans if it has it.

Swapping the front axle and suspension onto your truck might be the easiest route. I'm not sure about going all the way back to '82, but I think sticking a '95 4wd front axle and suspension on a '95 2wd truck is pretty straightforward. Then you'd need to get a 4wd trans and t.case for your truck (could possibly use the donors, see above). If ratios don't match you'd want to swap the rear axle too.

You've got lots of options. None of them are easy, but most are doable.

 

My trans in my truck right now is only 6 months old and would hate to have to get rid of it. Isnt there something called a new process transfer case that fits 2WD transmissions.

 

New Process is a brand. There are a lot of different models of them. But I think the one you're thinking of is the divorce-mounted NP205. Divorce-mount means that it's not attached to the trans, so you run a very short driveshaft from the trans to the t.case input. So yes, you could use that, but then you need to make up a t.case mount and get everything lined up. Likely to make it a much bigger job. By the way, there's a regular (or "married") NP205 as well, so if you go this route don't just look for an NP205, you'd need the divorced one.

The next question people ask is whether they can convert their 2wd trans to be a 4wd trans. Yes you can generally, but it means completely disassembling your trans to replace the output shaft and the tailshaft housing. It's usually easier and cheaper to start with a 4wd trans.

 

what did you have before you put in the 4:10s for the 302 and what is your final ratio in the 5spd

 

I'm not sure what you're asking or who you're asking. But since the only 302 with 4.10s and a 5 speed mentioned at all in the thread so far is my Bronco in my sig, I'll assume you're asking about it.

I bought the Bronco with 4.10s and the stock 302 and 3 speed manual. I don't know if the 4.10s were stock or if they were installed by a previous owner.

My 5 speed is an NV3550 out of an '02 Jeep Wrangler. I don't have my records available to me right now, but looking it up in the internet I found a reference to it having an OD ratio of 0.78:1

 

Yes i mean Nothing Special, if you dont mind me asking do you like the 4:10s? what is your mpg on the 302 in the truck? Have you ever ridden in something else other than a 4:10 behind the 302. ?

 

I get about 13 mpg, but keep in mind the height of a Bronco with a 6" lift. It's also not quite as aerodynamic as a brick, and it sure ain't light. I'd think an F-100 would do better.

I've also got to say I'm not a big fan of the 302. I don't like running truck engines over 2000 rpm very often, and the 302 doesn't make much power down there. I'm sure if I wound it out more I'd get a lot more power, but I'd prefer a 351 (or probably even a 300 six in a pickup). But that's me.

Personally I'd prefer taller gears, maybe 3.55s, to keep the engine running slower and quieter. But the 302 doesn't really want to run slower (keep in mind my 0.78 overdrive and 33" tires).

 

see i run 32 inch tires and i have a .699 finals gear. Im very tempted to put a 4.10 or possibly a 4.56 lol. I dont take long cruises really but Im scared to do it then just absolutley hate it. I would love to test drive one before I buy one with a 4.56...

 

I did a calculator and at 70mph if i had a 4.56 gear I would be at 2422 rpm. as of now I am at 1859rpm. so it wouldnt be terrible but definitely different.
