you aint going to gain much stroke from a 2.200 journal that is reduced down to say a 1.888" journal diameter...
a legit level of power making engine is going to have strength issues...make it a forging or a billett....
I do not think that by the mannor if his question,
post reply #9 is correct..
only issue is that most 2.200 journal cranks will not be the correct width between the shoulders to fit a PAIR of 1.880" journal rods.
some cranks, depending on maker and how the oil holes were located and drilled will not accept the smaller 1.88" journal..
...the oil hole passsageway will be thin or break thru...
other issue is the reality that you will have to buy an ODD length connecting rod or piston to get it all to fit.
just buy the correct CRANK with the stroke that you want
proper balancing is allways an issue with the cranks that are over 4.75 stroke...!!!!!!!
