272, 276 cams

[Tessie McMillan]

OK, so you remind me I had another dumb question. Pardon my technical 
inexpertise, but what is "overlap", and what is "advance"? I'm guessing 
at least the latter might be related to timing, but I don't really know. 

If I put in a .... higher lift, right? ... cam, what am I doing to improve 
the performance? Do I take more advantage of combustion/compression in the 
pistons, and why? Would I need to run a specific octane gas?
