if you must adjust your timing do it properly... use the cps or dizzy... and only adjust it if you know for definite what you must change it to
if you change the cam gear onto a different pin you will knock out your timing terribly.. it will be in limp mode.. it won't rev out past 2500rpm (or at least on the gte... what with electronic ignition and all)
i believe they're 1deg each pin? not sure.. haven't measured... have no need to as i have a cps
