7.3 radiator

Ive got an 89 350 with the 7.3 and the radiator has sprung a leak. Wanna use it as a good excuse to upgrade to a larger aluminum one. My thing is that the one that i found doesnt specifically show it to be a fit for the 7.3 trucks. Would a radiator for a 460/7.5L truck be a direct replacement? Or should i keep looking?

The 7.3 radiator is huge, I doubt you are going to find anything aftermarket that is bigger. The 460 radiator is smaller for sure.

did some digging and it looks like Summit Racing carries it for $100 less than Mishimoto does lol. Now I'm just wondering if I'd want to go ahead and convert to electric fan or not. My reasoning behind that is for the sole reason of having my A/C work more consistently even when stopped. Right now the A/C works wayyyy better when I'm cruising versus when I'm stuck at a red light. The least I'll do is install a pusher fan to the front side of the condensor

I'm not necessarily looking for bigger, but more efficient. or at least just as efficient

Autozone sells radiators with lifetime warranty. They're aluminum. Buy diesel specific only. The little 460 rads are not large enough. If you're interested in electric cooling fans:
