Also, bullet says not to use the lifter bore tool for measuring any cam specs. If roller, must use a lifter because of the wheel size. Mine are .810 wheels. Doing this does seem to get more accurate measures.
Uh-huh...couldn't agree more...that fancy looking CompCams tool caused me a massive headache as I attempted to degree my mild hydraulic roller. Eventually, degreeing off of an actual roller lifter got me the matching numbers.
Agree. The Comp lifter bore tool is good for centerline method where lifter diameter / roller size just needs to be the same on each side of max lift, but not good for open/closing events. For opening / closing events use the lifter that will be run.
