Apparently there is a center hole which align the cam lobes like stock, then if you want to adjust the cam timing you rotate the sprocket till it lines up with another hole.

there are like 7 holes or something right, well according to cat cams the very center hole is the closest to stock. you line the white mark on the cam gear with the that hole. both holes on the gear and on the cam will line up. that is how you know where the timing should be. the other holes are for retarding and advancing. if you run the the larger pitch cams like you are supposed to they are 10 degrees for each hole. i ran the smaller so its 8 degrees each hole. i just put them at stock for now to get a base, i may want to play with them later to see if there is any power gain. __________________
That makes it easy then! Also read another post where a guy pushed a dowl pin in through both holes once he had it set - to ensure the sprocket doesn't move.
Should be good to go then.
If this info (which apparently is in the instructions) had be offered by NVS SVT or timeless - we wouldn't have speculated all this time.
This is for both of you guys!
It's not in the instructions (there are none). This was all from a NECO member, who explained it to me a month or so again. Also from the pics that I have there are more than 7 holes on the CAT cams. The reason I never posted it is b/c it sounds like someone else did the work for the guy and he didn't know everything to 100% confidence. The last thing I wanted to do was give people the wrong idea. I posted pics of them when I saw them with whatever info came with the cams and I left it to everyone else to draw thier conclusions on how to go about it. Had CAT been more diligent in their installation documentation this would never been an issue, but that is not the case.
These cams are not in my posession, but if I had a set I'm sure I would have had this all worked out myself by now. The problem is when I saw the CAT cams I didn't have a stock type cam to compare it with nor has anyone snapped some pics of the two next to each other. Until then I am less than likely to say it is a simple task.
