So now we need to figure out an easy way to de-stroke a 235...
Then you'd have a 216- - - -or actually, about a 224- - - - -somehow I doubt that would be an improvement! All the stovebolts have going for them is low-end torque!
However- - - -reboring for a set of aluminum 235 pistons is a good way to pep up a 216 when you rebuild it. They have the same wrist pin size and compression distance as 216 pistons, just a bigger bore.
