I trying to figure out how to put a motor out of a 1206 IH turbo diesel in my 1980 f150 4x4. i have seen it done with a 78 f150 4x4 with a allis chalmers motor. so i know it can be done but i cant find anything online about it.

 

Well, you would need a bell adapter to likely a SAE bell so that you can find a transmission to hook up, then you have to figure out a clutch setup to do it. The 1206 motor is a heavy monster for the application, as well as plenty tall.The adapter mounting on the 1206 is the same as a 1266 if I recall, just that the 66 series has a wider frame and center section, so then you find an adapter for a DT466, as they are basically the same motor. (DT466 is also the designation for the tractor motor in the bigger of the 66 series. 06 uses the DT407 or DT361, depending on the size of the tractor.)There is a gentleman that goes by Perky on here that has a Perkins from a Massey in his 79 F250.

 

Not trying to hijack, but thought I would share something I recently learned. A friend of mine is a diesel mechanic at the local Ford dealership and is quite adapt at modifying and changing things. He knows I have a 1986 F150 with 4.9L and 4 speed OD manual. He teased me recently with the lead... "I have a diesel that will bolt in your truck".

He has acquired a mid 80's bread truck which has a 4 cylinder [M4B?] Cummings engine. The chassis is a Ford van with Ford 4 speed manual transmission [w/o OD]. He ran the VIN and found that the chassis was originally equipped or to be equipped with a 4.9L, so either the bread truck supplier bought and replaced the engine or possibly Ford sold the chassis w/o the engine?? Anyway, if one wanted a diesel in their F150, this describes another way to do it without the driveline conversion headaches.

 

That would be a cummins 4BT

 

What he said. A BT 4. They came in quite a few bread trucks but i have never heard of them bing ford. They typically used a GM trans

To the OP. a 1206 enging is pysically the same size as a DT466 as mention earlier. they are monsters and require doghousing the firewall and using a electric fan.

BUT a DT360 ia the same size as a 5.9 cummins(but built better) and would be an easier swap( seen one put in place of a powerstoke in a superduty)

 

Cummins had a "repower program" for both Ford chassis vans and GM vans. So both versions are out there.

 

Most early bread trucks were factory equipped with a 300, and some were re-powered with a cummins. These are highly desireable finds, as they contain most everything needed to put the cummins into a ford truck. I'm keeping my eyes open for one myself......

 

i have the new process 435 trans in my truck i dont know if that can hold the torque of a diesel or not

 

Not those diesels it won't. A 4BT or maybe 6BT, but not a tractor motor.
