I bought these Stage 4 Cams from Fast by Ferracci years ago as part of a Stage 4 Piston and Cam Kit for a 996. I do not have specs of the cams. I believe these are NOT drop in cams but you will need valve and seat work to get them to accept the correct opening and closing shims but I am not sure about this. I cannot refund them if you did not read this and did not mod the valves/head. What ai can guarantee is that they are FBF Stage 4 Desmoquattro Cams.
These truly are a ‘If you know then you know” set of cams. I tried to get more info by emailing Fast By Ferracci a couple years ago but they had been closed for awhile.
This is just for one set of Ferracci Stage 4 desmoquattro cams, the other set is just for comparison purposes.
Thanks for looking, please check out our other listings and response!
