"we moved the Crank Gear advanced by four notches. Each notch at the Crank is two degrees adding up to (eight degrees total) at the Crank"
FWIW I read the paragraph about where the cam is at couple of times and could make no sense out of it whatsoever. I've been at this engine building this coming up on half a Century and couldn't get a grip on it and I don't have or have never had any cam gears with "notches" on them. About the only timing sets I could move without offset keys were the 9 keyway sets and each movement of the crank gear REQUIRES the installer to use a NEW reference point or "dot" to line up with the "dot" the cam gear. Early Rollmaster sets were not well marked and the instructions sent with then as useless as the toilette paper you doddled last time you sat on the crapper. I've seen very experienced engine builders screw that pooch up pretty good when using Rollmaster timing sets when they deviated from "dot to dot" and started using the advance or retard keyways.........FWIW.....

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
