302 motor conversion

[roadtripper69]

I have bought a ford diesel motor and tranny out of a school bus to repalce my 302 in my deuece. I was wandering what kind of tips anyone can give me when converting over to a manual transmission. I used the search option and got a few ideas just wondering if there was anything major to worry about. I will also be looking to unload my 302 motor and tranny nothing wrong just want to go diesel will be complete minus carb I would like to get 400 for both

Boy I would love to have your old powerplant for that price. Unfortunately we're a ways away! Since your using a diesel engine you have no choice but to keep the original air over hydraulic brakes, so you'll be fabricating a mount for the air compressor. The easiest way to do this is to use a tight fitting piece of thick steel tubing that slides through the large bolt on the bottom of the compressor oil pan. Then start building the engine mount for it.

Try and keep the original radiator if possible. Otherwise any old Harrison radiator out of a Chebby will work. The mounts can be made out of thin steel plate cut in little short sections and bolted to the grill assembly in the headlight socket area.

Personally I like to keep the trucks 24V using the existing 302 generator/regulator. No wiring to change! If you stick 24V sending units off a M35A2 onto the diesel engine you can also keep your stock 24V oil pressure and water temp gauges. The previous owner of my truck modified the original generator mount by keeping the "u" shape section of steel and cutting off the rest. He then welded a large flat piece of iron to the middle of it so it looks like a giant
T mount.

You will need to figure out how to hook up a clutch peddle. Since you got the engine and trans from the school bus is it possible to get the brake and clutch peddles and replace the old brake peddle with the ones off of the bus? I'm assuming they hang from the dash and not come up through the floor like the original.

 

[roadtripper69]

I have already figured up a way to use the bus clutch pedal going to retain stock gas pedal an brake pedal. How bout the gearing I know I will loose low range but with a 5 speed manual will I be ok on power. I am not looking to run 80 just want it to be able to pull good.

 

[Gunfreak25]

Other than the above, making the new motor mount brackets and transmission crossmember is all super easy if you know how to weld and have a little creativity in you.

 

[Gunfreak25]

It may do just fine without a low range considering your axles are 6.17. What's that motor rated at anyway?

Post up some pics. I'm doing a cummins 4bt swap in mine. I'll be using a spice trans from a m35a2 and a transfer case from a WWII cckw. I have thought on a bit on the pedal issue but that's down the line. Good luck.

Would anyone be interested in a complete 302 out of a deuce and tranny

 

[roadtripper69]

Let me see what I can do on a cab and doors. I traded an early deuce to a guy a few years back and I think it is still sitting. I will pm with info if I have any luck.
