In my hellcat swap, I’m running a factory hellcat radiator ( under 200 dollars), and a 100 dollar dayco dual fan setup I bought from Amazon. The fan assembly bolts right up. It fits almost perfect, I just had to drill 2 extra holes. I have a 26 inch core support, which fits the radiator perfectly. You will have to mount an expansion tank for it. Factory hoses line up also. Have under 400 dollars in whole setup, and runs under 190 on hot days. No reason to throw money away on the other options.
