Cam spec

[BiGBoY]

Hello all ! I want to know where can I get the spec of OEM camshaft's. I'm looking for replacing mine, but before make a choice of cam I want to virtually-dyno my engine with the original cam and with those of each year. My engine is of course a 231ci.

have a nice day cruising your Buick!
