I modified my 82TQC to ~250-260 hp 8 years and 100,000 miles ago. I have
had no problems with the engine or the driveline. I replaced the stock
clutch @ 125,000 miles. I average 19 mpg and have to pound the car to 
get it lower than that. MANY other things have broken or worn out, some
of which just amaze me (the gas tank for example). I think of the
drive train as bulletproof. I did have to replace the exhaust manifold
and its studs but I think that is considered normal for this car.
