Hey guys Im getting conflicting info on stock rocker ratio for a bbb 455. trying to pick a new cam. going to run stock rockers. is the ratio the same for 70 to 76. I have a set of 72s and 74s. any help. thanks Kirk
70-76 is more or less 1.55.. the alum rockers have slightly more ratio than the stamped steels, but nothing to worry about. JW
