Has anyone had any success keeping a 500 hp 383 stroker with a 3000 stall cool with a Champion Radiator in a first gen Chevy II? I have about to come to the conclusion that my 3 core Champion radiator is very restrictive and is difficult to get enough air flow through it with an electric fan at idle. I have experimented with several different fans, including a 1990 Taurus from (from a 3.8L V-6). Even with the Taurus fan, it is creeping up to 230+ degrees when it is over 90 degrees outside at an idle. Naturally, when I get over 45 mph, it starts cooling back down.
