I have read about taking the pistons / Cyl/ off a 650 and installing them on a 550 block..6 speed gear box the advantage ,, is there a thread already on this .. ? Also I have heard you can bolt on a 650 head to a 750 for extra compression.. again is there a thread on this ,, Thanks for your help.. always asking questions ,,

the 550 has a shorter stroke than the 650 and 750(bout 2mm). you might be able to machine the block or case to get that problem solved tho. is the bolt and cylinder spacing the same? if it is, why go for the 650 jugs when the 750 jugs would be a fit too?
if you are just looking for a bump in CCs, wiseco has a 615 kit, might prove to be the easiest way to go. good luck

The 650/750 juggs will NOT fit on a 550 case. The studd spacing is different.
