would say 106hp instead of 96hp on the id plate in the engine bay, twin su's for a l series are real easy to find, have two pairs if anyone wants them, carton of woodies a pair!! lol. I personally dont like su's, well not the hitatchi nock-offs anyway, the british su's are a far better carb, but if you want power then the right cam and twin sidedraughts webers or dellortos are the go. my 2cents anyway.
