[71sierragrande]

I would keep the original, numbers matching, engine in it at all costs with that kind of mileage. Plus, it would seem a little weird to tell people the truck has only 7,000 miles on it, but its on its second engine(maybe its just me?). If you dont need the truck as a driver any time soon, I would rebuild it. That truck deserves it. Either way, have fun, we are all jealous. BUT...I sure wish GM would have thought to go with the extra odometer digit back then, right? My truck ONLY has 164,000 on it. Or is it 64? Or 264? Doh!!
