I've got a friend that doesn't really know much about cars, but he's always talking about his dad's chevy. I asked him what he had in it and he said "it's a 350 with a three quarter cam." I asked him which cam it was and he said "I told ya, it's a three quarter cam." I've heard this term from time to time over the past few years. WHAT THE HELL IS A 3/4 CAM?

Please enlighten me.
