VN1700 pistons to raise 1600 comp ratio

[andyvh1959]

I suspect the 1700 pistons have a different compression height (wrist pin to top of piston) than the 1600 pistons. Also, the 1600 fixed wrist pin is larger diameter than the smaller wrist pin in the 1700 full floating style. And the 1600 journals are larger diameter than on the 1700. So that all means I have to get custom rods made to make the 1700 pistons work in the 1600.
