Can anyone help, im rebuilding a highish spec st170 engine for my Fiesta mk1. The engine builder has just informed me with news the inlet cam is a bit gaff so I need to get another one. Now im considering uprating the cams.

Can anyone please give me some suggestions? the engine will NOT be running VVT and will be mapped on MS.

I have looked of a few sites and most only offer a cam for the black top or silver top.

Any comments or advise would be most appreciated
