170ci to 210ci stroker

My personal opinion: To me stroking a 170 is not an option, unless you are racing where rules dictate you stay with the low deck engine. It is much cheaper to just use the 225 engine. Even though you lose RPM capability, you gain torque.

The main reason I use the 170 is, I had a few of them left over from my "stock eliminator" days, and no 225's. Just used what I had.
