Hope this works.
You are looking at a 1959 Chev 261 into a RH drive Chev military 1940.

Installed a YF as per CarbKing and love it. Had a 3/4 inch steel adapter home made to facilitate the installation of additional vacuum lines for the wipers, PCV and vacuum gauge.... it is actually a crude repro of a stock item for that period.

Now look at the clear green nylon line. I had to use a steel reducer...... a male to male brass into the T fitting and the heat sender to an after market mechanical gauge. Everything tightened snugged with plumber's sealer paste. DO NOT OVER TIGHTEN ....... this was during the testing phase and we had a 1/4 turn valve inline that we could shut off the steam return line.....run the engine.... then open the valve and see all the air bubbles/froth purge itself to the radiator. Eventually all the temp rubber/nylon lines we replaced with solid flared steel lines.

Top speed 44 MPH at about 2900 rpm........ or half that in Low range 4x4........ and yes it whines like a banshee......cruises nice at 25 to 30 mph 23/24k.

hoping that the greatly reduce photo comes out OK.

Bob, how about a picture of the truck? Is it a CMP?

How accurate is your water temp. gauge? It looks like the sender doesn't get much water circulation?

Iam trying to set up some pictures on the Gallery but having difficulties.

Yes Ed. it is a CMP made in Oshawa, Ontario

Thermostat is a 160 degrees and the gauge never gets above 165 degrees. We believe that there is enough coolant flow out of the head.... by the bulb.....and out to the radiator that the reading is accurate.
We opted for a low temp thermostat because the engine bay is like an oven. On cold days I use a cardboard on the rad to let it get warm quicker...... never over heats or register any higher than 165. Radiator is sealed tight with a hidden overflow tank...... cooling system is not pressurized. There are NO provision for a heater........... comfort was not even a option.
I had the radiator re-cored with a 4 rows of tubes as the original.

I am afraid to look.... I think I finally got it

The first bolt was cut off the snow plow frame....in process of disassembly....and the finished product. Fingers crossed.

For the purist....... the roof is being worked on...... and the cargo box actually belongs to a model cab 13 circa 1942. I am re-engineering a proper 2B1 cargo box from 3 rusted out hulks as models.

Asking out of curiosity, not criticism:

Why the extra plate under the carb for vacuum plumbing as opposed to the intake manifold port?

I always liked CMP's, could never find a Chevy one.

Reply to JW51

The plate was essential due to the tight engine compartment of the cab 11 CMP. It was drilled an tapped for brass fittings.

The location of the factory manifold vacuum port sticks out the left side over an inch and the engine cover is barely 3/4 of an inch....Manifold is now plugged with a common pipe plug....... engine cover originally had asbestos insulation..... I am currently running mine with no insulation..... in the summer the heat transfer to the COE engine cover is enough to scorch skin on the right leg of a passenger if he is wearing short pants. I have since found some ceramic cloth that will be installing both for heat and sound deadening.

Such a plate was a stock item but almost impossible to find today.

Pictures......

Parts are hard to find so we scrounge for parts vehicles all the time...... our back field is our warehouse of about 36 parts vehicles shared between 3 of us working on CMPs,,,,The top one is a HUP ( Heavy Utility Personel) and the one under is a two axle 4 ton CMP trailer.

some even walk to our place

THANKS FOR THE HELP AND ALL THOSE WHO WERE PATIENT
