Finally, my first 360 and goals for it! I'll be asking a lot of questions.

I'm confused. The shop manual goes on about how important it is to have nb 1 cylinder at tdc on the compression stroke before removing the cam and be sure not to move the crank after this. Are you saying I should turn it over to tdc on nr 6 cylinder, align dot to dot and then turn it over to nr 1 again???

Just out of curiosity, why cant I just install the cam just the same position as the one I took out?
yes you can do it in the same position you're at now, just use a straight edge to line up dots. its just easier to align them in #6 position, especially if you don't plan on degreeing the cam, which i'm sure you'll hear lots about if you're not!
