I've got 186k on mine. As long as the block itself doesn't warp or crack you can keep rebuilding it for a pretty long time. As for how long it can last without a major rebuild, I'd estimate 250k miles or so, that seems to be right around where most engines start needing major internal components replaced like the rings/valves/bearings/etc.

250,000 if it's maintained properly and not flogged.

There are obvious things that will affect the longevity of your motor. In addition to proper routine service avoiding overheating is VERY important. Using proper coolant, thermostat
and having good hoses is important. High RPM racing and abuse are things to avoid. Then there are those popular bolt on aftermarket power adders some folks are fond of. If you want longevity and reliability I'd avoid those options. Frequent checks under the hood are especially helpful on older high mileage vehicles. Good luck!

Most modern engines can be expected to last at least 200k... Tolerances are much tighter and engines are built a lot better than they used to be, so you don't have to tear the engine apart for a full rebuild every 100k like with older engines.
When I hear about an engine lasting over 500k miles, I'm not really surprised. Most people just get paranoid and rebuild their engines too early. I've taken apart a BMW V8 with 239k miles and the factory cross-hatching was still there, along with the bores still being perfectly in spec. Even the rings were fine!

The person I sold my 2k TA has gotten up to 286K miles so far. No rebuilds and no internal issues.
Do regular maintenance and don't abuse it and it will last a long time.

The engine is the last thing I worry about. I'm more worried about things like the EBCM going bad
