Can anyone tell me if a four speed manual tranny with a manual overdrive from an 87 f150 with a 302 can be installed in a 1970 F100 with a 302?

I really want a 4 speed manual with overdrive for my truck and i have no idea what will work, which bellhousings match ect.

 

As far as I know, any transmission off of a Ford 302 or 5.0 will fit behind any other Ford 302 or 5.0--the bellhousing pattern is always the same. As for the truck, however, there may be a few modifications involved. I'm assuming that the 4-speed is a toploader, and if so, it should be a bolt-in swap. Anyone else maybe know a bit more on this?

I have the same swap in mind. I have a toploader out of a 76 Mustang II that was behind a 302. It is not the original motor or tranny from the car. I am quite sure that they both have the 28 spline output shafts...

 

Hmmm, probably not a toploader but an AOD. Might also be a three speed toploader, with OD. OD usually wasn't counted with the toploader.

 

It probably is a SROD. i have heard some say that they are not too strong. I don't have a high horse mill, 140 Hp and 240 ft-lbs. The 5.0 it was behind was built, maybe 200 hp, but the tranny is in good shape according to the guys son, who drove it a for a week before it got wrecked. My main concern is if it will fit in place of my current 3 speed without a different length driveshaft. The overdrive 4th will be a welcome addition, as most of my milage is on the interstate or highway going about 70-80, and my loud exhaust is not very pleasent at that speed, even with 3.25 gears.

 

Thought I would bump it.
I know that a true top loader has 8 holes in the bell housing, and the SROD has 4, so I will check when I get a chance.

 

What would the id tag be for the SROD?

The easiest to spot is the 4 bolt bell housing of the SROD (single-rail-overdrive) and the speedometer pickup is on the passenger

 

actually those codes posted are not SROD. they are overdrives but the easiest way to identify a SROD is the SROD! single rail overdrive means the shifter assembly is part of the cases and is operated by a single rail like a late model 5 speed. on a SROD the tailshaft will have a pocket and tube that is the shifter assembly and there will not be shift levers on the outside of the trans. if it is an orion overdrive it will look just like a toploader 4 speed and won't have an integral shifter. the SROD is the worst for strength and the orion is weaker than a toploader but makes a great trans for a street car (i have one in a 62 tbird behind a 390 and have never had any trouble)

here is the david kee page on orion overdrives:

and here is the only web picture i could find of a SROD:

and to try and answer the original question, yes you can use the late model 5 speed (4 O/D) on your older engine as long as you have the correct balance and diameter flywheel. ford has two engine balance figures (28 and 50 oz) for the 302 and several tooth counts for flywheels. basically all you will need to do is count the number of teeth on the late model flywheel and then get an early flywheel that size. it is really quite simple and easy. hawkrod

 

I saw that the picture you gave was from an ebay auction in grovetown, about an hour drive from here, so I may buy that one, or another if the price is right. My question is if I could use my flywheel I have now. I also have a clutch with only less than 2500 miles on it. Will all of this be usable? I am fairly sure that my drive shaft will have to be cut, but I have an uncle that will do that for cheap, and I can move my trans. crossmember with no trouble.

 

i would not recomend using a SROD transmission for anything other than keeping the barn door open in a breeze. they are famous for blowing up behind 4 cylinder 2.3 mustangs. a SROD would never hold up in a pickup with good gears as the torque multiplication and weight of the truck will shatter the transmission gears like glass. hawkrod

 

Oh well, the search continues. The other tranny I am not sure of the type. It has a case that *looked* like the toploders, and the shift pattern is

It was not the original motor or tranny, the VIN says it was a 177 V-6, and I could only see the tranny from under the hood. I am going to look at it this weekend, so when I get a positive ID, I will post it.
