Lets assume you just put in forged pistons to a compression ratio of 9:1 and used stock rods. Then set it up to be a 500 HP engine.
I gotcha Tom.... nudge nudge... It's kind of like many of the non FDA approved drugs that guarantee weight loss. Just because some people take the drug and loose weight doesn't mean the drug did it....nor does it mean it didin't.
For all the naysayers on the stock rods strength...who has even broken a rod? I know there is a well known person that believes they strech, but that theory has changed a couple times too.
