The maximum RPM the Packard V8 will turn depends upon the camshaft, lifters, valves and springs used. The OEM engine will not reliably turn 5,000 RPMs. The valves are long and heavy, the springs are weak and the hydraulic lifters will pump up. Every manual transmission '56J I have ever torn down showed damage from at least one dropped valve.


This is one of the reasons why I chose flathead engines over the Packard V8. Can't drop a valve that has no place to go.
