Note the 6 bolt rims, the narrow fenders, the wide channel under the driver's door and the vertical tow shackles on the front bumper. I think it's a HUP.

Hup rims..... frame looks smallish like a HUP......engine is at least a 235 late 50s or even better a 261...... that hole in the valve cover should be connected to the air filter inside the paper element..... my guess is a 1957-59 261 truck engine....... give away is the large 6 sided brass fitting on the intake manifold just below the carb......

See if you can read the serial number on the head just between the valve cover and the carb....

also..... just above and almost behind the starter motor.... see if you can find the "captain"s" bars...... two one inch long raised vertical bars about one inch apart....... just like the Captain's bar......

Best solution for the water pump is to go back to a regular cone shape... or flower pot shaped pulley that was there originally for the 235 or 261.....

Too bad you are so far away........

Try taking some pictures underneath of the front axle/rear axle to see if they are HUPs....

Also..... above the rear axle.... is the frame straight and horizontal or do you have a curve up on the frame over the axle......

Parts for the water pump may be hard to find inyour location but plentifull here in Canada.... shipping will be a pain but if we can help you just holler..

Can you read the serial number on the flat surface next to the distributor...stamped in the machined surface....

..... and how is the throttle connected between the gas pedal and the carburator........

I still think you may have a very desirable 261 truck engine....

I wondered about that, but didn't want to say so because I saw that the oil lines to the filter were the smaller lines like the bypass setup rather than your large lines for full flow. The other puzzle is now the air filter that you say should be a paper element, were the paper element ones made for the slipon carb or only the screwdown carb? I wondered about the throttle linkage not passing just below the water outlet from the head, possibly removed for maintenance but I didn't see mounting holes when I first looked (I didn't notice 6 bolt rims so perhaps wasn't looking carefully enough).

Yes, you must be right! But it had it's chassis lengthened, didn't it?
