hey
i was thinking of getting a Crane Cams PowerMax camshaft...i need something emissions legal. i see that they have one for a 3.1L, but it only lists the CID next to it as 189, i have a 191...does it make much of a difference? do i need 2 cam shafts for a V6? how much HP should i expect from this? a noticeable difference?

thanks

mike
