Charles Navarro from LN im sure would have plenty of knowledge to throw at you on this topic. Just observation though the limiting factor would of course be the stud spacing but in talking with a reputable engine builder over the last year he related a story in which he used 993 piston and cylinders before any aftermarket version was available in that bore. With that route you can hog out the headstud holes in the cylinders or weld up and drill new holes in the cylinder spacing size then use the 993 heads.

The bigger the bore on an older case the thinner the cylinder base gets to accomodate it before you have to machine the case. Im not certain if Charles said it would be possible or not or if he had done it but I disctinctly remember having read about slip in 100mm bore cylinders for an SC case.

Ken care to elaborate on your motor? With the 102's are you running a 70.4mm crank or the 74mm piece? With the prior does that mean a 3.5 litre motor and with the latter a 3.7? crazy cool
