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..?
The camshaft has a lobe separation center line. I don't know what it is, I'm too lazy to look it up....so for the sake of conversation, let's just "say" it's 108*. Most cam cards say to install cams 4* advanced. That would be 104* intake center line FROM the 108 lobe center. Some say 5*.....but "whatever" let's just say it says 104* for the sake of argument. That's 4* advanced. You could probably go down around 100* but I think I would stop at 102*. With a lower compression engine, advancing the camshaft picks up cylinder pressure and pumps up bottom end torque at the expense in a VERY small reduction of top end torque.
Conversely though, Retarding the camshaft timing takes away a good bit from the bottom end while adding a very small amount to the top. Usually, advancing is the way most people want to go. Unless you're roundy round racing and trying to cut down on traction loss coming out of turns and that kinda thing.
