Lower sprocket is simple and cheap,
adjustable sprockets more cost , more accuracy but at a higher level of complication, and the potential at slip .. both on the cam and at the adjuster, cam is easy spot weld them
when i put my stroker crank in and bigger spacer i started retiming the cams, first checking the base settings knowing they would be a couple degrees more advanced going from .080 to .120 and found my exhaust cam had moved, considerably ...
cleaner sprockets, more locktight and tighter bolts, hope they hold tihs time cause its not going to be pretty if they move when i'm in top gear near the rpm limiter for 4-5 miles
