[QUOTE="bclapham, post: 765754, member: 25565"] OK, i am bumping this one as well. lets take the case of a 4mm stroker, the pin is moved further out by 2mms. if we use the same rod, then we have to decide what happens with the extra travel, you can either take material from the head, or shim the cylinder up 2mm with a base place. assuming the cylinder was setup before to produce peak at 11K RPM, how would we alter the cylinder to keep the powerband the same, ie not turn the engine into a stump puller or top end screamer? eg how do we shim the cylinder and what ports do we alter? also, i am slowly getting around to reading the Bell book. It says that if the piston goes below the exhaust port at BDC then this seriously effects the gas flow out of the cylinder.....i am sure this would be a problem with the stroker at BTC???????
