I don\'t believe it !!!!!!!!!!!!
 

Just seen a 748 on ebay. Its got an 916 sps head and put's out a claimed 119 bhp:o Maybe an 853 with spshead but I would'nt have thought just the head alone.

I know where your coming from Jon and thats meant to be rear wheel bhp from what I recall, wonder what I would get if I put SPS heads on my 916.
