yeah i doubt it, but i would run one cause you can gain noticable power out of them, just paint it and nobody will know the difference, even if they check for it.

ya i might just have to run what i got for now but i was just hoping by next year they might change it i dont think you would gain any horse power out of it do you really?

yeah its somethin to with the cylinder walls i think, i was read on another forum that one guy gained like 70 horsepower, and when they built it they added like 20 pounds of weight, idk what it was, but he said it was to make cylinder walls stronger, but it didnt mess with the power any when he ran it. idk how it does it, but it does it crazy. i know a few guys that run them, they used to run GM 400 blocks, and said they woouldnt go back, and they run better now. so to make a long story short the little m is the way to go.
