That's what makes this forum so cool...and confusing..lol. Now see, I like your response better, because I get the cam.. What's that mean to set it a few more degrees advanced..?
Well...this might be a little confusing at first, but it's "need to know" for doing engine stuff, so here goes..
Camshafts are ground with a certain Lobe Separation Angle (LSA). Let's use 110° as an example here. Now, your cam card may say something like "these specs are for an installed centerline of 106°..."
That means they're having you install it 4 degrees advanced (or they may say their cam "has 4° of advance ground into it"--same difference.) It *should* then match the valve timing events shown on the card.
But, that doesn't mean you can't advance it a few more degrees (this is what RRR is saying)..so you could install it at 104° for a total of 6° advanced, or even 102°...you get the idea. Generally speaking, advancing the cam moves the power band down (helps bottom end) and retarding the cam moves the power band up.
It's done during the cam degreeing process...so if you haven't done that before, start researching or find a buddy/shop that can help you. Some guys just "stab it and go" but there are many reasons to degree or 'verify' the cam so for me it's not optional..
