Where's the best place to get a fan shroud and radiator for a 360?

Guess I can see where my next paycheck is going then.

I'm pretty sure the thermostat is working though. I was bleeding the cooling system today. Air and hot fluid came out after a bit.

I didn't. It was a roadside repair, but next time I get paid, I'll probably buy a lower temperature thermostat and test it out.

The radiator in it now is about an inch smaller than what a 360 comes with. There's no fan shroud on it either. It over heats and stall after about 10-15 minutes of driving at about 45 mph.

So I bought a 1971 F100 with a 360 big block and 4 speed manual transmission a few days ago. The seller has told me that the radiator is out of a 300 straight 6 motor. Could this be the reason why my truck is over heating? I've replaced the thermostat and burped the cooling system.
