Need opinions on radiators

my Duster came with an aftermarket 2 core 26" radiator and everybody(rad. shop & so called experts) said it won't work with a 360/430 hp motor with 4 spd. Wrong!
I had a backup plan and a correct core to rebuild($$). I installed the aftermarker radiator because that's what I had at time of install. It worked great and worked great again when I got my a/c going. No overheating issues at all, in any traffic situation in Fl.
I'll get the correct radiator rebuilt/recored and installed eventually, just for show.
