Okay, now that I have replaced my 305 with the new 350, I am trying to figure out what to do with the 305. First I plan to tear it apart and use it as a teaching tool for my 15 y/o. But, then what to do... Is there really any difference in the BLOCK between the 305 and the 350? Or is it simply in the crank and/or the rod length? Could I take a 305 block, bore it 030 over, and install a 383 stroker kit that includes the 400 crank and the new pistons and all?
