I got 235K on my 02 5.3 - still going.

 

Pulled one out of a buddies truck at 300k due to a lifter coming apart but other than that it ran like a champ..

 

260k+ On My second truck both 5.3's, I've replaced every accessory, suspension, steering and brake part in the past 8 months.... but never pulled a valve cover or dropped tranny on it. The truck still drives like new, w/ the exception on the 22's and the slow windows lol

 

x2 on the slow windows, and the rust... errrr 02' with 119,000 just getting broken in

 

Just clicked over 247,000 miles on my way to work today. Runs strong and looks great!

 

245,563 runs great

 

I have a little over 250K, runs low 15s holds 60 PSI of oil pressure at 75 MPH. Original 5.3 untouched, original 4l60E (vette servo at 168K) and on the 3rd 10 bolt lol.

 

3rd 10 bolt? What'd you do to the first two?

 

260k on an 01 and runs great. I did just have to put all new injectors (3 failed at same time, maybe bought some bad gas?) and it uses a quart of oil between changes. Put an 06 tranny in around 200k I think.

 

Just one tranny? For real?
