Quite the low mileage find.Wow a whole 100k!
My machinist said there's nothing wrong with the engine to half a million miles if you can swap out the intake seats for ones with proper (ever so slightly tighter) tolerances and don't overheat it.I’m at 308,000 miles. Original engine.
I did have to do the headgaskets at about 250k, so I had the heads done professionally and did the timing and oil pump myself.
These engines aren’t nearly as fragile as people claim. Literally any aluminum head can drop a steel seat. The 5.7’s can do it, Chevy LS engines can do it. ANY engine can do it.
