I'm sure sleeving that block would make it last a very long time, that's just a teeny stroke, I WANT TO BUILD THAT !!!!

Yeah but all you ever see is everybody sayin "stroke it" all the time. There's a stock stroke 400 makin 1K HP. How long you think a similarly built engine would last at 650-700? Probably a good while.
