highest mileage ls1 whats the highest mileage ls1 with mods you guys have seen still running good or hell just running, the mods can be spray,boost, h/c whatever im just curious to see how long stock block bottom ends are running?
There are a few C5 Corvettes running around over 300,000 miles w/o much more than basic maintenance. I know one guy gave his to his sone with 315k or so on it and his son still drives it. He got a C6 to replace it. I believe the car had a few clutches, a new trans, and a new water pump. Other than that oil changes etc.

I met a guy around here that has 200k on his 98 Z28. He has got a nitrous kit on it, I don't know how big but it was 75-150ish I would guess. And he had true duels with no cats and a tune. It seemed to be runnin like a top!
Mine has 143k on it about to do lts,stall,gears and maybe some spray. These cars are like pretty little women you do all the little things and wash her up and she will let you beat on her a little bit.

You know how you guys have beaters for the winter? This Z28 is my beater. I drive it all winter except when there's snow on the roads (these suck worse than anyhting I've ever seen in the snow).
I only change the oil at every 6k, I use Wal Mart tech 1 oil, and I only change the filter every-other time.
I bought it way back when for $6800 when it had 75k on it, it was pretty nice then. I've now put an ADDITIONAL 100k on it, and have had no problems except for a trans sun shield (probably due to racing/burnouts). Engine loses about 1/2 quart of oil per 3k miles. No smoke. Some piston slap when it's cold, nothing major. Right now exhaust sounds like crap probably from the rust of the Pennsylvania salt.
I expect to get minimum 200k on this stock original engine.
My only complaints would be the headlights look like they were sandblasted/fogged from all the miles of dirt chipping away, these should have been glass or something more durable. The supposed stainless steel exhaust is rusting and there's a rust hole in the bottom of the stock muffler now, I was under the impression that stainless never rusts, guess I was wrong there. Lots and lots of rattles. Other than that I'm happy with this beater. These cars are rock solid. Gives me a lot of confidence in my Vette's driveline seeing how strong this Z is.

impressive 300k on a ls1 thats something i would have to see to beleive if thats true thats just plan awsome, but in all i thought it would be a cool topic to discuss you know not your run of the mill thread
I've got 189k it was virgin LS1 when I got it. With LS6 intake, 85mm MAS, lid and catback it did 13.2 @105 with no tune. I just did hooker LTs and a tune and WOW it runs nice! Should be maybe 12.99! No smoke, plugs perfect and Oil psi is 60 above 2k.
Highest I have seen was 297,000 miles. Was an old customer/friend of mine that drove his 98 C5 around the country for business (sales). He was driving the car 1000-1500 miles per week for a long time. He moved to Virginia, but as far as I know he still has the car and it's still running on the original engine.
I've worked on several in the 120-180K range.
