Max GVW: 14,000lbs that huge truck had 318 gas engine only.
did someone put in the
Cummins V6 engines 354ci six cylinder Perkins Diesel engine. back then vast choices of engine /transmissions were offered
and all are rare.
most of these back then, me on the road too a loaded truck was going 40 to 50 mph; under even small hills.
the speed would be limited to max diesel RPM. then.

Either a 1.6 Liter 2 barrel carburetor 4cylinder engine with single over head cam found in 76% of that years dodge colts. or it's a 2.0 Liter 2 barrel carburetor 4 cylinder engine with single overhead cam found in 24% of 1974 dodge colts

I think the biggest slant sixes were 225 cubic inches with a 1 bbl carb and 145hp@4000rpm and 215#/ft of torque@2200rpm. A D500 may have had something else, but if it's a "Slanted" engine, I'd bet on 145hp. Seems kinda small for D500....

5.0 L or 5.9 L V8or 3.9 L V6 ???

check with a windscreen retailer /fitting shop as they will have the specs for the screens and what vehciles they fit.
