My 92 was overheating and I replaced the thermostat and that didn't fix it. I thought it might be plugged also, but it turns out that there was too much debris between the condenser and the radiator. Took the radiator out and had it flushed since I was that far into it and the shop said he got a little gunk out of it, but that it wasn't that bad. He also pressurized it to some crazy pressure just to see if it was still solid on the inside. It held and now I'm back in business. No more overheating. The thermostat is about a 15 minute job on my 454. Easy to get to, easy to replace. I'd try that first since it's cheap. Let us know what you find out. BTW, those aren't cheap radiators and having one replaced was going to cost me close to $1500. That's why I tore into it myself.
