Cold Case or Griffin radiator in a 1970 Duster?

I’m thinking of getting a radiator from DeltaPag. They make a single core 1.5” thick radiator. They claim many guys on the power tour with 1200 plus horsepower have their radiators…I don’t have much room in my truck once I put that small block in it with a 671 on top. That 3” belt drive system takes up all the space, no room for a mechanical clutch fan.

I don’t really want to hack up the front of the truck to move the radiator back.
