Where to start for a 416 kit?

Can someone explain what is done as far as the 416 kit goes? I was wondering if the cylinder has to be bored? Any websites would be helpful as well. Why is this called a bolt on kit? Thanks

Yes, the cylinder is bored .80 over. You get a new .80 over piston, gaskets, and most people get a new cam with it when they do the 416. Marcums sells this, TC, Sparks, just about anywhere will have it.

There is more info on this site about the 416 kit that is allowed by the law I think.:confused:
