What's the go to for radiators?

Thanks for the replies so far! Unfortunately the Jegs radiators are all V8 with driver's side outlets. So Champion seems to be the budget go-to.

For another option, does anyone know of radiators from other applications that fit with enough fan clearance? I swapped an Aspen / Volare radiator at one point (it later sprung a leak though, hence the circle track radiator), but these days, that's even harder to find. I've noticed that '70-'74 Chevy Nova radiators are about the right size and have the outlet in the right spot for a slant six, but I'm not going to try one without confirmation.
