I think a lot of people confuse the 5.7 converted Olds with the 6.2 Detroit. The 5.7's were in fact installed in 1/2 tons in 80/81. Their failure led to the introduction of the 6.2 detroit. It was a better, but not great replacement. My dad and I ran an 82 Suburban to 350k miles and it was still going, not using oil even, when someone offered me $800 for the engine alone. Since it never was a barn burner, I bit, and parted the truck out. He said that 82 blocks had higher nickel content, which was why it still had such good ring seal. He rebuilt it and put a Banks turbo on it.
