OK so i have an 83 f250 4x4 originally a 302 with 4 speed manual and I purchesed a 1969 Lincoln continental with a 460 and auto tranny I am wondering what I would have to do to accomplish this swap? I know I would have to add tranny cooler lines, detent cable, and a vacume line from the modular valve, now what else, will I have to swap drive shafts? Also how would I bolt transfer case up to the automatic, please if anyone has done something simmalar to this please be thourough and list any kits you know of that I may need

 

Well you'll either have to find a 4wd trans or buy an adapter for yours to bolt the transfer case on. Not sure how the length of the trans compares to what you have now but you'll probably need to lengthen your front drive shaft and shorten your rear shaft. You might need the frame mounts for the 460, don't know if they're the same as a small block motor. You might be able to use your current cross member but maybe have to modify it a little. And you'll probably need a radiator for the big block motor.

 

Need to chech out all your accessories...PS, AC, Alternator.

My 82 has a 460 swap and it was fairly straight forward but it is not 4x4. My PS connected right up to the PS from the 460 and the alternator was in the same location.

Has different motor mounts but you should be able to get those from an 85 (I think that's when they started using the 460 in the F series).

This one was pulled out of a TBird and the tranny lines, modulator vacuum line and radiator came over with the motor. The radiator was a little shorter so some blocks were used to space it up off the support. I have since put a radiator from an 85 in there and fits perfect.

lower radiator hose is different as well. Original was just a big bend coming off the WP to the radiator but hit the steering box. A hose for the Truck as a bend in it to clear the box.

Check on your ignitions system. Depending on what year your motor is coming from....there may be a different ignition system the motor is wired for and may not be compatible with the wiring in your truck.

Exhaust is obviously completely different. I run headers with dual exhaust. What's in your truck now likely will not fit up. You may be able to cut and have some new pipes run from the manifolds to have the connect up with your old pipes...or go all new.

There were lots of other little things to swap but none too major. Again....this was not a 4x4.

btw....still uses the stock transmission cross member for the C6...not sure what was originally in there to be honest. Driveshaft looks original too.

 

And make sure you bring that kickdown lever with the swap....they are hard to find. I had to use a cable from Lokar

 

A 69 engine will have breaker point ignition.

The frame mounts for a 460 are way different from a 302 as are the front springs.

You will need to get an output shaft and adapter from a 4X4 C6 transmission.

At least on and F250 you shouldn't need to worry about rear axle strength, front maybe depending on what it is.

Radiator, if you have the heavy duty cooling, it will work, the physical size is the same, I would just use an external transmission cooler.

Accessories, the 69 engine stuff is probably layed out totally differently from a truck, it may even have a Saginaw power steering pump. Unfortunately I sent one of the biggest pieces of the accessory system to another member on here, or I would have a complete set from an 86 engine.

One item for future reference, a 69 460 is internally balanced, starting in 79, the truck 460s became externally balanced so the flywheels are different.

 

Ok so I found a big block C6 from a 88 f250 4x4 also picked up a floor shifter out of an 79 f250 at the junkyard also got the crossmember as you previously stated about the ignition system what would have to be changed?I do know the 302 and the 460 I have are non-point ignitions. Does this mean they are the same

 

you stated on your original post the 460 is a 1969 right...it should have points. If it don't, then it's been converted at some point.

 

So I should be ok with my setup I have? Yes the 460 is a 1969 block and yes it has been converted by the previous owner. It has a brand new distributor

 

Not sure...would depend on what was put in there. Many aftermarket distributors have completely different connections than stock and may or may not be compatible to what you currently have in your truck.

 

Let us know where you are and maybe one of us can help you in person.

 

Groveport Ohio and that would be appreciated

 

The transfercase and the extension housing have to be matched.Meaning that you can't use a NP 208 transfercase with an extension housing from a 1356 transfercase.I found this out when I did my 302 to 460 swap in an 88 f250.I used a 1980 C6 with the 1356 T/C from the 88 and re used the original drive shafts.I used L&L style swap engine mounts on the 302 tower mounts.Looks like a factory install with LT headers.Installed a 33 gal 1988 Bronco fuel tank/pick up in place of the dual tanks.Ran a true dual exhaust.

 

But I have a c6 that had a bw1345 bolted to it, and I sold it with a np208 installed. And all the t-cases fit the 4-spd transmissions..so am I missing something...???????????

 

I don't know if it's a year specific thing,but my 1980 np208 adapter would not work with my '88 1356.Both were from c6.I figured they were application specific.I recall it had to do with shifter installation and maybe speedo hook up.Couldn't mount the 1356 shifter to the 208 adapter.Two different designs for shifter mounting.
