What owners wrote
Vehicle taken to dealer for excessive valve noise. Inspection showed excessive wear of valves and valve guides...out of specs. Engine heads and valves to be replaced under warranty.
The 7l 427 engine has a valve failure problem. The valve heads break off inside the engine while running. This happened to me as I was driving along a highway at 60 miles per hour not accelerating braking or turning, in a very remote part of texas. The engine seized up. This is a known issue by GM with a much higher than expected failure rate yet has never had a service bulletin nor recall. The car had 18,000 miles on it at the time and had never been to the track or abused in any way.
