I have to concur with the majority opinion above. Although I'd rather not have the big turbo 3208s, the natural 210 is well within the stresses and cylinder pressures of the original design. We rebuilt quite a few 185-225 HP versions succesfully, but found various other stress cracks in the 250s that made us turn toward other wet sleve designs for our higher HP needs. It's a very good engine. But like indicated above, check on who and how it was rebuilt. It's not something you can slap a set of rings in and go. My two cents.
