You are right about the parts for the BBC. The SBF is a totally different animal and is built totally differently. You can't compare the 2.
Having built many 408 windsers, we have tested everything you can put into one and the parts that are being used by this gentleman works the best with the proper cam profile. We have come up with our own cam profiles that do work great on the street but is a real monster when you get hard into the gas.
