Don't break his heart and tell him that the 959 was using nikasil plated alloy liners, sodium filled exhaust valves, and a dry sump years before any Corvette...

The LS7's (from the LS engine family) are modern day monsters that are clean from a emissions view and get decent fuel mileage . The cylinder walls are very easily replaced. The service life of an LS engine is a extremely long one.
Big blocks were produced way later than 1972. I had a 2000 Chevy 3500 pickup with a 7.4. My dad still owns his 1997 Chevy Express 3500 van with a 7.4.
