Looking to replace the stock camshaft in my 67 C/S 330 4 barrel Air Cond car. Went thru the service manual and can't read the valve timing chart on page 6B-28. Looking to find stock numbers for duration of the valves, so I can compare original to future new ones. Thanks for your help, Brian

 

Oldsmobile cam specs are notoriously optimistic. Unless you really must have a stock cam, talk to Mark R (cutlassefi on this site) for a cam tailored to your application.

 

Not currently looking to buy one, just needed stock specs to see how much of a stronger cam i would like to buy verses the stock one
