i would only count engines that required no overhaul or very minor internal repairs.
like timing set on engines with fiber gears.
or seals,gaskets,ect.
the closest i have come is 395k and still counting.
85 olds 307
1 timing set and 2 intake gaskets.several valve cover gaskets.
whatever oil and filter was on sale is what it got at every 3k.
its in a wagon that has been used as a pickup.
loaded heavy and driven hard.
