I need help to decode a suffix number. I'm told that the engine I bought over 20 years ago is a 1966 327. The Suffix code is Z1 6638526. I'm assuming that the first two digits represent 1966. 1966 -327 Horsepower ratings according to two web sites, show 325HP and 350Hp @5800 RPM for the "Z1" RPO. Is this also known as an L-79 engine? What should the intake and exhause valve size be for this engine?
Any information would be appreciated.
Thanks
