You learn something new everyday. How long will an LA small block hold up at 550 horsepower

I Know a guy that ran a 408 stroker like 10 years without refreshing it. Just oil changes every year . The Engine was build by Dennis Maurer in Tempe Arizona . It was running on a 68 Barracuda , Super Street Car.
Mopar crankshaft , block bored with deck plates, Edelbrock heads, compression was like 10.5-11:1 . The Engine was running and it had a problem with the water pump motor and overheated , thats how it died .
