Why do you Advance a Cam
Why do you do it. I just ordered a H/C package from TSP and my cam is the Torquer V3 would I have to advance it and if I did what are the benefits. Can you get the tool at autozone.

The main reason to advance a cam is to move the powerband down. For instance, I had a big cam in my 370 iron block a while back with a powerband of 3k-6800, so I advanced it to move the powerband down to a more useable area for the street. However, advancing the cam is usually only done in situations like I just described where the cam isn't properly matched for your goals. With a proper setup, no advancing is needed on your part (only in the grinding process where you may want some advance ground in for theh proper intake valve closing and exhaust valve opening). Also, there is not a simple tool for it. You take the front timing cover off, undo the sprockets and adjust the cam.

You have to have an adjustable timing chain Did you mean adjustable timing set? Even then you don't have to have one of those. You can have the stock sprockets and just take the cam sprocket off and adjust it how you want it.

On an SBC, you can use offset bushings for the cam sprocket, offset keyways for the crank gear, or adjustable timing sets of many varieties. Some use a crank gear with multiple keyways ground at angles ranging from 8* retarded to 8* advanced. Cloyes also made a hex-adjust set that allowed you to loosen the bolts that secured the cam gear, then turn an allen screw to align the dot on the adjuster with several retarded or advanced settings.
Actually, a quick search seems to net the same methods for LSx engines as well.

I didn't mean to adjust using the cam sprocket, just taking the cam sprocket off so you can move the chain on the crank sprocket without having to pull the pump. Moving it a tooth on on the stock crank sprocket is like moving it a tooth on any other sprocket, but yes, you have to degree the cam to make sure this way. It's just an option if you don't have an adjustable set on there.
