confused - or just a stupid question

I am not sure how the cam was installed. What does it mean to be advance? I have never raced the Comet in the 1/4 but he has, and runs low 16's. I know having my tires spinning would only decrease the "et" times if I took it to the track, but this isn't a race car, just a street cruiser. I expected the tires to just engulf in smoke. Because a friend of mine was telling me I need a better gear, like a 3:23 at least. A 2:76 will not give me any traction with whats been done to my engine. Besdies I need new leaf springs since mine are in pretty bad shape.
