There is no "number" or size anyone can tell you because not many have tried. (much easier and cheaper to just use a 2.5L block) Your best bet is to show you block to your local engine builder and get his idea. If you go bigger then an available oversized piston (IIRC .040) your next problem is to find a piston that you can use, if you go with a custom piston your looking anywhere from $550-600.

FYI: (stroke x area of bore) x number of cylinders
Area of bore = pi x radius squared<p>75 x 69.6 mm is the bore and stroke of the 1.8
mm x .03937 = inches

pi = 3.142<p>so cc's = stroke X 3.142 x bore x bore / 4<p>so using your numbers of 75mm for the bore and 74.2 for the stroke you get:<p>cc's = 7.5 x 3.142 x 7.42 x 7.42 /4<p>= 325 per cylinder<p>or 1946 cc's or 1.946 liters for the whole V6

Basically if you bored the K8 100 over then you would end up with a KF, but spend more money for it.
