True they don't make them any more, but the specs are available to have your stock 235 cam or 261 cam reground to match the McGurk specs. Joe

Joe,
Any idea what the lobe lift would be on those performance cams? I'm wondering exactly how much more lift a performance cam would have had over the 261 cam I bought. Any idea why is there no performance cam specified for the 261 exclusively?
BTW,
GM Canada put the 848 head on the Pontiac 261 strato-six from 1955-1962.
