Sure, but it won't bolt up to the frame mounts, transmission, injector wiring, coil wiring, the alternator won't bolt to a chevy engine, so you'll need the GM pile with its wiring, including a different gauge cluster / dashboard. To run the alternator, injectors, coils, and engine sensors, you'll need the very trouble-prone GM engine computer. That computer won't run a Chrysler fuel pump relay. The fuel pressure will be wrong too so you'll need the GM fuel pump. That won't fit the fuel tank opening, so you'll need to replace the fuel tank and filler pipe.

Only a GM transmission will bolt up to a GM engine. You'll also need the GM transfer case. You'll have to have a special drive shaft made that fits the GM transfer case and the Dodge rear axle. Same with the front drive shaft.

The AC compressor won't bolt up to a GM engine so expect to use a GM compressor with special hoses that can be made by most radiator shops. NAPA can make the hoses you'll need for the GM power steering pump. The GM radiator hoses will not match up to the radiator inlet and outlet. The same is true of the exhaust pipes. Might as well use the GM exhaust system so it will line up with the exhaust manifolds, and will have the fitting for the proper oxygen sensor. You'll need to splice the back half of the Dodge exhaust system to the GM front half; otherwise it won't line up with the rear axle.

GM six cylinder engines are about 100 pounds heavier than similar Chrysler engines, so you'll have to install a pair of front springs for a V-8 engine. Chrysler is the only company that has been able to make an engine run right without a Mass Air Flow sensor. You'll need to modify the air intake hose to except this sensor.

Wouldn't it be easier to just find the right engine?
