Agreed, but he was concerned about too much power from the swap, these are good for cruisers, hiway riding, it'll have pretty good torque, 4X is 8-1, these are 7.6-1, with some carbon build up it's probably now 8.5-1, I would still consider the 068 cam while it's out, the 067 is the station wagon family car cam, the 068 will boost it 50-70 hp easy, great heads for a blower application.
