Agreed. I've had two different LT1's in the past six or seven years and I have never had an Opti issue. It's simple, keep water away from it and it will last forever. A leaking waterpump will leak out the weap hole right onto the Opti (bad design) and potentially take it out. So long you keep an eye on that waterpump and don't hose the engine bay near the Opti it will last over a 150,000 miles. People make the mistake of replacing their Opti's with aftermarket units which is the other reason they go, the geniune AC Delco units are the only ones that should be in those cars.
