Is it possible to advance or retard a 3 bolt camshaft? How would you do it?

Typically the crank gear has 3 positions, 0, +2, -2.

Here is a more exotic one for mopar.

Is there a brand that is recommended from an accuracy and quality stand point?

Thats almost a loaded question, hard to answer. What kind of engine? Bone stock? Big horsepower? How much valve spring pressure? Lots of things determine what should go in. I like double rollers, cloyes makes a njce setup. Prices vary from 20 to 200 depending on what you need.

The engine is a bone stock 440 six barrel. I will be using a Mr. Six Pack cam and lifters and whatever valve springs Mr. Six pack recommends for his cam. The cam I bought from him is a 3 bolt cam.

This should more then handle it with a small amount of adjustability. Next step up is about 100 bucks.
