Ok, well I thought I understood something, haha. I thought that the increased stroke of 3mm on the bottom added up to .2L to go from 2.3L to 2.5L, and that 3mm was taken off the top to keep it in the cylinder bore. I understand reciprocating and 3 on top and 3 on bottom and all. Have an overall grasp, but one thing I don't get. 86mm stroker crank, and 3mm is taken off the top, reciprocated means 6mm is taken off total. Ok, if so, why aren't you still at 2.3L? Not a big deal, but sounds strange to take the extra stroke back off, so I'm confused there, haha.
Also yah, sounds like your talking about taking more off at the bottom to further stroke the crank. Guess what I was thinking was if you could get a taller block, say from the guy that does the aluminum ones, so that you could use the longer rods n taller pistons so that the stroke was as long as possible. New sleeves and machined, welded block extension? haha, don't pay attention to me. My brother used to get so mad at me because I had no engine knowledge and asked stupid questions. Common sense in these things is based on experience!
