I've been told that can be done by flipping the rod/piston 180* in the block. My biggest interest in the long rod is closing the combustion area to increase compression. The lighter piston with it also being a better Forged and not cast piston. The offset of the 2.2 will or should duplicate the offset that would be acquired when reversing a stock 225 rod combo. All this looks good when I read it, but I'm trying to put it into a build that someone has already done. The money spent on decking the block, shaving the head, modifying the pushrods, would be much more than me purchasing the 198 rotating assembly for $150. The total project with motor, I don't want to exceed 8-10k
