Even Two Fully Blue printed engines will run differently. They would run close But each engine built has it's own characteristics.I learned that when I used to run and Build BB chevys.To me it also wasn't worth the extra Bucks spent on having the motors blue printed (if you knew what you did on the first one and it didn't work, What good were the blue prints?) So i would have to pretty much agree with Joe.Even the Quailty of fuel would also make a difference as to the Out come.
God doesn't like ugly.
