Question about 250/C-5 Swap

My wife has a '61 Ranchero with the original 170 and 3 on the tree. I have been wanting to convert it to an automatic for her. I hear the 200/C-4 combo is a good match. However, I have a line on a 250/C-5 for a good price. I'm an experienced wrench but have not done much with Ford sixes. Will this combo. work in the little Ranchero? Anything I should look out for? Tips/advice, anyone?
Thanks

Howdy Gerry:

Yes, it can be done but it is no where as easy as the 200. Even the 200 swap into an early round body is not a "simple" bolt in.

Know that the 250 is taller, heavier and wider at the pan then your original 170 or a 200. If you decide to go with the 250 be sure to use the 250 engine and frame mounts, which will allow the engine to sit lower and in the right spot for hood and steering linkage clearance. Also know that you will have to fabricate a trans mount for the C5. Space at the front of the 250 will also be at a premium and have to be planned for.

The C5 is a lighter and more sophisticated version of the C4. It has a lock up feature designed to give better fuel economy. If you're after MPG the C5 is the way to go. The C4 is a better all-around choice.

My choice would be the 200/C4 combo. It will be a nice upgrade and fewer details that need "fixin'".

Adios, David
 
Thanks for the expert advice David!! Sounds like a little more work than I'm willing to tackle due to time constraints. Guess I'll keep looking for a 200/C-4.
Thanks again!

I'm gonna add a little more spice to the mix. I just put a 200 with a C3 from an 80 Mustang into my 62 wagon. After switching to a front sump pan and pick up tube, the motor bolted into the 62 mounts. I fabricated the rear trans mount. It wasn't hard to do. Here is the kicker. The 62, 3 spd. driveline mated to the splines of the C3 and bolted right in without modification. The speedo cable worked as is too, though I still have to figure out how much error occurs.

I understand that the C3 is not as good of a trans as a C4 but it has to be a darn sight better than the 2spd auto or 3 spd standard transmissions that came in our cars. The car is now running. I am currently sorting loose ends like nuetral safety switch, rewiring for the alternator and installing air conditioning.

Another thing I found out is that an S10 crossflow radiator is an easy fit. I picked up a little much needed space for clearance of the double pulleys required by the air conditioning.

I'll keep you posted after I put a few miles on the new combo and see how it works.

:D Wow Mike, that sounds like just the ticket!! My wife's just going to use this little Ranchero as a grocery getter and maybe take it to a few car meets. Nothing serious though.

Thanks

I didn't set out to use a C3, thats just how the donor car worked out. I was bummed at first when I found that the Mustang did not have a C4. When the driveline bolted up, my mind changed a little.

I need to put a few miles on her before I claim too many bragging rights about the swap. So far I have run her through the gears with the engine running while the car is up on blocks. The trans shifts fine, there is no noise, trans fluid leaks or obvious problems coming from having an early 3 spd. driveline yoke plugged into the C3 tail shaft. I saved the C3 yoke in case I need to switch it to the 62 driveline. I doubt that I will need to.

Other changes not listed in my earlier post are:

1. I had to change to the early water pump. The late one was too long. The 170 pump bolted up.

2. I used a 62 automatic throttle linkage. This originally bolted to threaded holes in the top of the 62 automatic bell housing. I bolted it up to the late bell by welding the linkage to a piece of 1 1/2 x 7" angle iron drilled and trimmed to bolt thru the top two bellhousing to engine mounting bolts. All the stock linkage hooked up to an early 200 carb. I will modify the stock 62 kickdown rod to mate to the C3. I probably should have used the cable throttle linkage and kickdown from the Mustang. Hindsight is 20/20.

3. I used a 63 automatic steering column so I could keep stock appearence. The C3 came from a floor shift car so the shift arm was backwards for column shift.. I fabricated a down facing shift arm that was tack welded to existing arm so that the direction of the linkage worked right. (This is not necessary if you use a stick shift.) A stock 3spd shift rod bolted up to the collumn shift arm and my fabricated trans arm after a little bending to achieve good mechanics. All in all, it was not to hard.

4. Most of my time has been with trying to fit air into a 6 cyl Falcon. There is not much room in the front of these cars.

5. If in the end this set up does not work to my satisfaction, I think a C4 will slip right in into place of the C3 with only a driveline change. All linkage etc. that I have fabricated should work with the C4 also.

Mike,

Thanks for posting this. Were you able to get a fan behind the radiator. Love to see some pics if you have them. I'm working through this with my 63.

Thanks
 
Yes, I am using a stock early 6 cyl. fan. I had to space it out about 3/16" to clear the double pulleys required for the air conditioning. I fabricated crossflow mounts using rubber mounts that came with a similar sized radiator. There is room for a single row or double row 30" wide x 16" high cross row radiator while not interfearing with the hood prop rod that stows along the top of the radiator. The V6 S10 that I pulled the radiator from had only a single row. I also have a double row of the same size that needs to be rodded and flushed if I find that I need to use it.

The horns will have to be moved forward or back along with the voltage regulator.

This radiator mod is overkill if you don't plan to use air. I only did so because I ran out of room for pulleys and that I will pull a teardrop travel trailer (800lbs) plus camping gear another 200-300 lbs. while using air conditioning. I don't want my car to overheat.


I don't have a digital camera so I don't pics yet.
