Radiator R&R and upgrade, OEM + ?

[Kriegs]

My rad in my 90 c1500 pos/project took a dive.....I eventually want to swap to an LS 5.3/6.0 -4l80e, it has a 4.3 5spd in it now.

I was wondering what would be the way to go on replacing the leaking rad with something that I could use on both the 4.3 for now and still be adequate for the eventual LS/Auto?

Is there an OEM solution, 454 rad,5.7 vortec years, 2500+ radiator, etc etc etc?

I've read horror stories about the cheap full aluminium one of ebay and the like, and the plastic china replicas breaking at the upper bung/hose on the tank.

TIA
