Mine is at 130,000 and is still running strong.

 

176k miles. Intake oil leak fix and optis. Valve covers never been off. Blew a head gasket after overheating it (clogged cat. converter).

It's had quite a few optis in the past 2 years (one problem after another). That was pretty much the only problem!

 

ive had a few with stock motors
108k spun a bearing after pullie install
formula had 215k on it and it broke opti rotor
new camaro has 15k on motor 80k on body and its fine...
friend has 175k on his stock motor with bolt ons its fine
another friend has 145k and it still runs strong just took out the motor and stuck in another one

 

Still runs strong on the dyno at 111,000 on the original motor. I have owned it since Nov. 2003 and have replaced nothing. I am the 4th owner and the 3rd one to road race it.

I plan on doing a new Opti, water pump and alternator out of paranoia more so than anything else.

 

146k miles.. still runs great and very strong, but lots of blowby.

 

119k on mine before I was spinning it to the moon and spun #7 rod bearing. My fault doing it on a stock bottom end but needed an excuse to tell the wife why I was in need of a new motor.

 

190k bone stock, replaced a couple clutches a rearend opti and waterpump, i decided to rebuild it when i was doing the clutch and there was nothing wrong with the motor, shoulda left it alone lol! hope the rebuild gets me another 190k

 

94K - Crank Broke. Was stock at that point.

 

What's up with all these cranks breaking.

 

mine has 123K on it, and still purrs like an angry kitten

only issue so far is what i think is either a bad oil pump or a bad gauge

 

142k on mine ... lets just say it hasnt been treated the best either ---

 

58k and spun a rod bearing, cam and bolt ons.

 

My 94 has 26k miles and is on it's third opti. The 95 has ~160k, and is still running the original opti.

 

My 94 Z has 177,XXX All stock. One Opti, one water pump, one fuel pump. Strong as ever, my daily beater. About 3 years ago it had ~ 140,XXX and I thought 150,XXX would be good enough & time for replacement. Bought a used 00 SS w/ 40K miles. The 94 is a better dependable car in my opinion. SS has BS issues like VATS. It pretty much sits in the garage waiting for the 94 Z to give up the ghost. Also have a 94 Vette w/ 120,XXX. All that ever wanted was 1 Opti & 1 water pump. I'm sure I'm in the minority here, but I like the LT1 better than the LS.

 

94 TA at 190,296. New opti at 120,xxx, 3 water pumps before then, just replaced gummed-up heater core, replaced entire drive line at 180,000, engine is in great shape.

This poor thing sat for a full year in 1998, and 2 years from 05-07. It's getting put to good use now though.
