Note that while the early S cams will give you alot more revving of an engine, they will not work with the CIS pistons (valve collision). So you would want to change the pistons to RS spec. Doing such will also give you a more sporting compression. Also, the overlap on the early S cam will not bode well with CIS. So if you want to go that way you will have to look for a new induction system. Anyway, Im planning on doing a hotrod 2.7 myself: twin plug, early s style cams, rs high compression cylinders, and a custom EFI system.
