in my opinion, unless you dont have the money to buy good parts there is no other reason to de-stroke a street engine. besides keeping pistons speed down with cheap pistons, i dont see why else you would ever do it. rod ratio is so minimal, or a negative power effect, that its not worth the money to get one rod over another, so thats no arguement.(dont start a discussion over ratio now please.)

you can be origional if you want, but i would advise going 408 before i went 320ci or whatever you after.
