95K on the stock opti and runs strong with mods. in signature. Assuming it passes a compression check, its going to get a nitrous kit installed next spring as well.

 

108,000 mods and time in sg.

 

At 134k, spun a rod bearing and in the middle of a major rebuild/upgrade. Also had to replace the Opti 4k ago. wasnt a good summer for ths lt1

 

126000 with boltons. Replaced the opti and water pump at about 90000 but other than that she has ran excellent and still does.

 

ive got 132000

 

I have over 100,000 miles on my 97 Mustang and my 94 Camaro but the Mustang only has around less than 50 miles on the brand new motor and the 94 Z28 is getting a stroker motor put in it in the next month or so.

 

i have 114 on everything but the engine. the previous owner had the first LT1 from the factory die at 62 and change. the one that is in it now has 52 and runs very well. aside from some road chatter and noise, the car performs very well. my close friend has the audi s4 6 cyl. TT awd 6spd 2001, that is the only car that i can compare to or give an appx. time listing, but i beat that car when we race from about 6 to 8 car lengths appx. good or bad that is the only thing that i can compare my car to. LT1 is a good engine.

 

i got a 112K and it still runs strong i ran 13.8@103mph when i first got it will only 50K, and that was stock just loudmouth,so i sure i would be faster now,the motor is still strong,hell i am door to door will my brothers SS and that good enough for me right now, I want to put a cam put i dont know if its a good idea with all those miles on the motor, mostly freeway miles

 

119,000 on stock '95 Z28. Rebuilt tranny @ 105,000, among a few other minor replacement parts. Spent most of it's life in California, now in Mich. So far so good.......

 

185K km's (=115K miles) on the clock. If taken care of, these cars can last a long time.

-original opti
-oil pressure is great
-doesnt burn any oil
-105 mph traps with intake/mids/exhaust/madz28 tuning

 

i have about 101k in hard miles full bolt ons. and i just blew the rear but the motor is still strong

 

111,000 completely stock

 

125K Pulled really hard last time it was at the track. And spun a bearing.

 

122.000 with the mods in sig and original OPTI. It's my daily driver and I put 140 miles per day all highway driving at 85 - 90 MPH. I race anything and everyone that will go for it. I drive this thing hard and it takes everything I give it. I had the Trans rebuilt last month and replaced Breaks and rotors this past summer. Keep the maintenance up and it will be like the energizer bunny and keep going and going and going.........
