hi just stripped down 2 blocks i had lying around and removed the camshafts, i have 2 camshafts that look very similar, both have 270 stamped in the centre, but all the other numbers are different, and also 1 is painted red in the end section of the shaft near where the vernier bolts on.could anyone tell me off these numbers if they are standard or uprated?? at the end where i mentioned painted red there are 2 lugs on one side and 1 lug on the opposite side these are noticably different sizes on each shaft, the numbers are
cam 1 from vernier end 3/ f?20 270 13
cam 2 from vernier end 12/ f021 270 11
opposite side
cam1 from vernier end 5\ p m 13
cam2 from vernier end 6\ fish sign m 11
anyone any ideas???
thanks
