LOL I would like to see you build two 434" clevelands for what 7.3 would cost with the same power level and reliability. And I am a cleveland guy. For the cleveland to go to 434 CI you are into after market blocks for starters, then after market heads, stroker crank kit, custom pistions, etc, ect. I just built a 406 CI cleveland with my block and after market heads. The short block alone with the stroker kit was $7100.
