this is just to kill some curiosity I have. what are the effects of this in a racing circumstance? Is block rigidity increased? Do the metals used for sleeves hold more heat in the chamber. How big of a bore can be acheived with sleeves in a 292? do they hold up well in engines with extremely high cylinder pressures. Have any of you done this to your inlines with success. Haven't really been able to find anything on the net. thanks for the replies
