highest mileage ls1
Oh yeah, amazing how chevy can produce such a great engine... and then make it go to work every day for the weakest rearend they have ever made. I supose the only redeeming factor of the Fbody is that it's the cheapest ticket into LS1 world

My 99 T/A has 112,xxx on it and 80,xxx miles of that is with heads and cam. Car burns oil, about 1/2 a quart every 1,500 miles. Smokes sometimes too. Still runs great. No issues with the car. The only repairs or expenses other regular oil change etc has been a power window motor, a pair of O2 sensors, and a set of valve springs.
I have about 113,000. Had 75,000 when i bought it bone stock. Ever since then I started modding it. I am now running 10lbs of boost and making around 600hp. LS1 for the win!!
I have 82k on mine with H/C since 66k. I also run a 100 shot at the track and she's gone 11.64@121 here at 4400' and has never left me stranded. Hell other than routine maintanence and mods i've done nothing to it. 10 bolt is long gone though...
