Sounds like you have an air flow problem. I doubt moving the fan 1/4" will make any difference. What type of fan is it? If it's an aftermarket flex fan I'd swap it out for something more original. In 1972, wouldn't that have a clutch fan assembly? I'm not certain but by 1972 most cars came with clutch fan assemblies. My 351 Windsor always ran hot with an aftermarket flex fan. I installed an OEM Ford clutch fan assembly and the temps dropped down significantly.
