i acquired this cam sprocket with a 'box' of z parts that i purchased awhile ago. what i know
person in the military purchased some cool z parts while stationed in japan
brought parts back to install on z purchased in the states
some of the parts in the box; new timing set, hks lightweight flywheel, mallory ignition and dizzy, new rocker arms & keepers, used timing chain & cam gear [help id this one-first pic], new adjustable cam gear [shown in pic]
odd cam gear has 8 holes around it vs. 4 holes, weighs about 16oz vs. stock about 24oz.
so, who makes it and is it a rare part?
first pic shows the lightweight, 2nd shows the stock look & weight adjustable cam gear.
