IIRC, the Northstar has the ability to run even when coolant is lost. I think it will stop firing on one bank for a few seconds and then alternate banks should coolant be lost. That way only one bank fires and the other is cooled by fuel.

Now, OTOH GM, Ford and Chrysler has been obsoleting parts for 10 yr old cars. In 30 yrs, you could get parts for your car whereas his Caddy might have a bunch of stuff he has to scrounge from junkyards.
