I had a 91 I bought brand new and put 98,000 miles on it before totaling it. Only problem I had was a burntout fuel pump due to clogged fuel filter. Also, watch for vacuum leak typically caused by cracked vacuum lines under the plenum due to heat and age. I have a 94 w/ 55,000 miles and my intention is to drive until the motor gets tired and then send it off to DRM or Ligenfelter for a rebuild ( roughly $13,000 to $16,000 depending on the level of hp).

My '91 has 97,000+ and still runs strong. The typical "wear out" parts (alternator, starter, plugs/wires, and some gaskets) have all been replaced. It does use more oil than I think it should, but certainly not woth tearing the engine down yet. Everything I hear says the LT5 is a very tough engine.

I have 124205 miles on the engine and use it as a daily driver. On the way to work each morning I run it up to 105 to 135MPH (private road 5Mi.) just to get my adrenaline going and to prove it can still do it. It uses about 1 Qt. of oil every 700 Mi.It's also for sale for $18,000.00
