this is probably a stupid question but ive asked a couple of people, what exactly does a AEM adjustible cam gear do? i can find an awnswer for this question

 

if you don't know what it does yet, it's prob best you don't mess with it till you do research. no offense but have you used the search function yet? I'm fairly new and I think it's in red font for a reason.

 

An adjustable cam gear on a single cam will allow you to "adjust" the powerband for better low end (advancing the valve timing) or more top end (retarding). On a dual cam you can gain power, they are best tuned on a dyno until the optimum setup is found. They are usually aluminum, which also lowers reciprocating mass.

It doesn't do a whole lot until you get an aftermarket cam or two.

Quick addition: This is how one goes about adjusting the mechanical timing of an engine. The ignition timing has nothing to do with this, so don't get the two confused

Also, SOHC or DOHC, they should all be tuned on a dyno for the best results.
