LOL! I sold my 318 with a 6901 to an older guy who has a 49 Plymouth. He's running the stock intake and BBD with that cam...he's happy so far...but concerned with gas mileage i told him "you'll be ok with that BBD..." but yes they are the street cam or classic cam i think the series is called...they have a series above that may be called performance series or something like that.
