That was my thought when i bought mine. I was looking at nnbs's and with 100k miles the damn thing were still like $20k. I figure i could totally rebuild a obs (or nbs for that matter) and have a brand new truck.
My theory assumed though that i could do most of the work myself and you need to have the cash to do it. A lot of people can get together $400 a month for a car payment on a 20k car but cant manage their money in such a way that they have several thousands dollars on hand when they do need a new engine.
That and you'll spend much more on maintaining the NNBS. They break a fair bit more IMO

Concerning high mileage: My Tahoe 1998 currently has 415'000 km and still drives without problems. I hope I manage with him the 500,000 km mark. :)

My '98 Tahoe is a daily driver, and it is at 458,000 km's (286, 250 mi). I would love to have the proper place to pull wrench on it, but condo living prevents that. I drive about 55 km's (34 mi) each way to work. I try to keep the servicing up to date and I am confident as long as I do I will be driving my Tahoe for a few more years yet. I am lucky to have found an excellent mechanic who does not shaft me, nor nickle & dime me to death.

This is good to hear! I'm sitting at 177,000 miles. I've had to replace various things over the last couple of years (read: nickel and diming) and the paint is getting rough, but for the most part the drive train is solid. I was thinking I'd have start looking for a replacement in the near future, but maybe not! Although, I do tow with mine a fair amount, so maybe I won't be so lucky.

I tow with mine also. Just always done regular maintenance and swapped out stuff over time ( water pump, started, etc...) I just try to always us new AC Delco parts and I’ve had no issues. I still have a lil fund set aside for that new 383 stroke when the old girl gives up on me

That's where I'm at; I can change out most parts mechanically and electrically. Drivetrain and engine is where I bring in somebody that knows what they're doing! Just had the oil pan changed due to a stripped oil plug. Thank you, crappy oil change chain store that still tells me I need new wipers and filters, when I just changed them a half an hour before going there. :mad: Were the DT and/or enigine fail, I'm sure I'd be replacing the vehicle. As much as I love it, it's a very utilitarian vehicle and was purchased to keep the wear and tear of a much new vehicle.

I tried searching and could not find anything.

So my question is, what do you consider high mileage on the 5.7 and what is the highest mileage motors on this site?

I have a 94 2-door Yukon with the 5.7 and 205k on it and would like to start using it for daily use. It runs great and has no leaks, previous owners kept it up.

Post up some of the highest mileage motors you guys have.
Mine has 340.000

Really? I bought a 1985 Caprice with a 350 / 700r4 in 2000 with 80K on it. Paid $1000 to an elderly woman who's husband had died.

First thing I did was put Mobil 1 synthetic oil in the motor. Slowly changed the tranny oil a couple of quarts at a time, with a filter change once at 150K. 19 years later I still drive this car 40 miles a day to and from work, I have almost 350,000 miles on this ride today with absolutly no problems. I have changed 1 alternator, 1 mechanical fuel pump, 2 headlights, and 5 sets of tires. And oh, I rebuilt the Qudrajet carb once myself. Yes, it amazes me too. It still has ALL the original tail-light bulbs, side marker bulbs and every thing else it came with. The front power windows gave up the ghost, the A/C was gutted by me years ago, and the power seat adjustment motors quit long ago.

All the glass is perfect, I put Z28 wheels and big tires, and a Grant GT wheel on it in 2001. In 2017 I replaced the shocks with Police packge shocks, and new fan/drive belts for the first time since original. This was the only money I put into it in almost two decades. It has started right up in -20 degree winters in Utah, when my Tahoe, and my Silverado refused to start. Never serviced the diff. This damn car won't quit and is amazing.

She burns about a quart every 4 months, but everything that count's still works. All emission equip't I deleted when I got her. Kept stock iron manifolds, but deleted air injection and cat for a single flowmaster. She sounds awesome, hauls ass when I need her to, and gets thumbs up going down the road. Even the stock white paint finish and body is almost perfect to this day. That's 37 years of reliable service, with tires being the only major cost.

Old school yes, but she amazes me to this day. And she lets my Tahoe and my Silverado sit in the garage while she weathers the rain and snow sitting in the driveway, ready to take me to work 5 days a week without fail.

So my lesson learned here is to Run Synthetic oil, slowly change your tranny fluid here and there, and talk to your baby once in a while while driving down the highway. It took 500 men and women to carve bolts and sheet metal out of steel, to make your car or truck, they kinda have a soul. Not so different from how our Forefathers treated their Horses for thousands of years before Cars and Trucks were invented 120 years ago.

Oh, what were we talking about. Yea, and a small block Chevy is capable of doing 400K if you maintain it with modern chemicals, parts, and yes...love.
