Taking bets(no money involved) How long will this engine last?

OP, if you had good oil pressure before teardown, and the mains and rod bearings look ok they should work fine,just put them back exactly where they were originally. You probably wouldnt even have to plasti guage if you didnt want to. basically you are cleaning it up and regasketing it. Im thinking about doint the exact same thing t o my 86 5.0Liter Mustang
