That looks like G.M.'s goofy advertised duration( don't remember what liftier rise,measured at...) , actually a nice cam over the Ram Air 4 308/320 advertised grind.(daily street/strip use..)without 4:10-4:30' s out back. It's tuning abilities here,closer thank you think... Both cars tuned well , ( no cam swaps,or head porting..) Choose the G.T.O.... Pontiac ,knew how to match engine parts...
