Looking on the Mopar perfromance parts page, I don't see any B/RB Purple cams listed with less than .430 lift. The stock cam as listed in the Mopar engine book is .410 lift. Something just doesn't seem right about your measurement. :scratch: You may want to take the rocker arm out of the equation and just measure the cam lobe directly off one of the lifters. And measure 3 or 4 different lobes to check for wear.
