I seriously believe that with the proper maintainence, the 3.8 will last well beyond 500k. My 3.8 lasted me from 120k through 140,001 k (still have the speedo/odo), and I beat the absolute crap out of it. Even with the rod bearings gone, it would still run (sad day). The 3.8 n/a when properly cared for, will last forever and a half, even with the headgasket issue.
While my current car is faster ('96 Dodge Neon SOHC), I really really really really miss my Thunderbird (aka: Pheonix), not so much the power (which wasn't awesome), but the style and ride the car gave me. I will never forget that car and I will buy another when I get the oppurtunity. In my 3.8 n/a tbird, I got awesome gas mileage. So goodluck with yours.
Just take it easy, and no prolonged donuts in the snow.... that is what spun the bearing in my 3.8 n/a... damn i feel dumb about that. also, keep an eye on the main bearing seal, it might e worth the replacement if you get your hands ona better torque converter..
