There's a good bit of fore and aft adjustment to the radiator support. So much that the radiator can most definitely interfere with the stock 4 blade fan. Thing is, the inner fender dictates where the rad support goes because they attach to the sides of rad support. My inner fender to rad support holes I don't believe have any fore and aft adjustment. Maybe some are elongated, I don't know.
Ran my newly rebuilt 235 several weeks before installing the front clip, including removal/reinstallation of rad several times in the "teething" process of my engine
That's how I know.
