I'm with you...no need for a fancy all aluminum radiator here.

A Spectra Premium radiator spec'd for an 81-87' Squarebody truck with a 454 (PN CU730) is only $120 or so from RockAuto and will provide all the cooling an LS needs and is a direct fit into the squarebody trucks with a 454 top mounting plate.
