good point, the assumtion I am making is the S damper is suited to engines similar to the S engine, ie reging upto around 7500 rpm, but that said the S crank differs substantialy from the std crank so god know what it is doing in terms of vibrations.... so hence my thinking of just stuff a viscous damper on and be done with it.

 

just for a bit of fun ive drawn up the overlap of all the large bore crank configs that sprang to mind.

If I recall, they were used to stretch a 1275, together with a 74.4 mm Bore to 1600 cc.  I've not seen or driven one in this configuration, however from several people, they say they are not great and make no more power than at circa 1480 cc and don't rev as well. Perhaps these days though, a 1600 bottom end topped with a 16 V head might be another story. 

 

Some grinding of the Crankcase and Gearbox Case is needed to get clearances too.

Yep,91 mm stroke and 74.7mm bores, making 1596, although I think I remember an article many years back where aldon did a 91.somthing crank to get somthing like 1608cc. Definitely not sure though
