ZZ4 vs 260XFI ???
I searched the forum and found alot of people are recommending the cc 260XFI cam for 350 TPI. However, I looked at the specs and, other than having higher lift, the specs are very close to a ZZ4 cam. Is there an advantage to going with the 260XFI over the ZZ4?
Thanks!
Thanks!

Yes. The XFI cam will have a smaller seat to seat duration but have more area under the curve. It is a much better cam all the way around.
