Re: 4/7 Cam Swap

Does it really give you anything extra? I was looking around for some
definitive numbers and I can't seem to find any. That would be a
nightmare for anyone working on the car besides the person that did it
though! Could you imagine the cursing while trying to get the firing
order correct if you didn't know it was messed with?
