Brad, I came up with this long rod L18W combo the other day. Instead of
the L20B crank you could leave the L18 in there, bore the block to 89mm
if it will take it for 1941cc. Use 89mm KA24 pistons with 34mm pin
height and 2.8cc dish and L20A rods (135mm)if you can find some.
+.2mm above deck. 41cc head gets ~10.6:1 CR if i operated the calculator
correctly.
Anyones thoughts on this engine are welcome.
Craig.
