Hello All, I am having no luck at finding the cam numbers for the #4387721 roller or its replacement, such as lobe separation angle, intake/exhaust duration and intake centerline.
I also wonder if there is a difference between round tooth and square tooth cam gears? Specifically, relative to the cam gear key slot, are the two gears teeth identical in spacing or are the key slots machined a couple of degrees different from each other.
