I know how to on like old muscle cars with only one cam...but how would it work on our lsj's with 2 cams?

 

...ignition timing? umm...electronically?

 

actually there is something where you line up the colored links on the chains with certain marks on the gears that spin them. Can't remember exactly. I'm sure that if you look on the left side you will see what I'm talking about.

 

yup.. there are 3 colored links on the timing chain and marks on the cam and crank sprokets

just align them and you'll be all set

just make sure to get it on the right stroke (i.e. not 360 degrees off)
