Ok I read that thread all 26 pages and didn't find the answer either yeah the stroke is 95mm but what is the rod legnth what rods do you use in the blue top h22 or h23

 

The rods are 5.551, .021" shorter than the H23a1 which are 5.572"

stroke is 95mm
main journals are 55mm
comp height of the piston is 1.201

 

wich is why if we use type s pistons it should be flush
