103k and runs like a champ! Powerwise, I think it's making more now than when it was new. I'm curious what the highest mileage is people have seen on these motors.

110,000 miles
its my daily driver making over 400rwhp
i think 200,000 is a good point to rebuild the engine or just get a new one. when mine hits 200,000 (assuming it gets there) im just selling my car and builing an efi 408 with an innercooled turbo

i just bought mine with 198,000 on it. other than a couple pretty massive oil leaks the car ran real good, I drove it a whole 1/2 mile before I ripped out the engine and tranny for a full rebuild. The body and interior is in good shape and for the price I couldnt pass it up

59,600. But the GD rear main drips a lil oil and has managed to coat my clutch with it. However, Ive heard this is a common problem with 5.0s...?

Mine just 241k and finally quit. As long as it wasn't abused it should last. Luckly the previous owner of my car was a nun and didn't do much racing(I think).

Yup, they are famous for that. Mine does a little as well. Not bothering w/ it until the clutch goes out though.

My "new" 84 GT has 277,800 miles on it of course the little 5.0 finally submitted and spun a bearing and forced the owner to sell. The previous owner did regular maintenance and never abused it. This car is still cleaner than most cars with a third of those miles.

Bought my 90GT with 72k..it now has 83k. I bought it from an older guy who had hip replacement surgery and could no longer operate the clutch. No problems except for a leaking rear main which will be taken care of next week when i change the clutch.
