This is for a 720 engine? The L20B rod is identical. Both are 145.9mm between crank center line and piston pin center line.

just putting this here to help clarify things. Connecting rods 
Center to center length, all use the same 21mm diameter piston wristpin. 
L18, L28, L26--------------130.2mm 
L16, L24---------------------133.0mm 
L20B, Z22S, early Z22E-145.9mm* 
Z20S,- ------------------------??** 
Late Z22E-------------------149.5m* 
Z24, KA24-------------------165.0m

They are incredibly long and if used on the shortest stroke engine (L16/18) the piston pin height would have to be around 25mm. That's under an inch and there's no room left for the rings above it.
