crazy lift from an F23 cam. Thank God for Bisi. Who said there's no F23 support? Can't wait to put this thing in.

Yes it is a regrind, I talked to Bisi and he said they optimized the cam based on my flow #'s and lift. I didn't expect them to be able to do this much without a hardweld. Thought some F23 owners might like to see the specs. Apparently there's something wrong with this thread.
