Okay, in my 90, I have a 28x19 3 core radiator that just went bad. Radiator.com is gonna warranty it. I want to upgrade it....should I get the 28x19 4 core (which is basically an upgrade for a K5)...or should I get the 34x19 3 core (big block radiator, which is listed for a suburban), they say they dont have a 4 core for a 90 burban..... Which one would cool better? I have two perma cool electrics for it...also might do the windstar setup and use the perma cools on something else /forums/images/graemlins/dunno.gif Thanks!
