I plan on rebuilding my '68 225 this summer or fall, is it possible, or any reason to, change it to 231 evenfire? Could the cam, crank and distributor from an evenfire be used in the 225 block. Also punch it out to accept 231 pistons? What would be the advantage? I live on an island and as a rule don't go much over 45 or 50, go to the Glades some and creep around the Big Cypress. Not really a speed demon.
