I think Mickmate is right. FE pumps are easily capable of generating 100 PSI or more. The pressure is regulated by a pressure relief spring in the oil pump. For a typical high volume oil pump for a 428, that spring is set to open at about 75 PSI. If the bypass valve and/or spring stuck, the pressure could shoot way up. I'd change the oil pump for sure.
