My 91 suburban engine (350 tbi) tries to overheat when I tow in the hills around here, occasionally climbing into the 240 range. I'm thinking about converting/changing over to a 2wd 454 radiator which is wider by 5'' and a 4 core. Anybody done this conversion? I know I'll need a big block shroud and a new/wider pads, anything else?
