Comp Cams XFI Cams

How does this cam look? Look at the lift numbers. The intake is more than the exhaust. This is the cam they recommend over the CC306. I have been searching for info about this cam but I guess its still new.

Re: Comp Cams XFI Cams

I can see nothing really wrong with it, If you have an excellent flowing exhaust and well ported heads on the exhaust side a dual pattern cam is not completely necessary. But there are probably better cams out there depending on your set-up.

It looks simular in timing to the XE 230/236
