Looks pretty good to me, and resembles most cast intakes used for heads up NA racing. Well until you make it a cast tunnel ram anyway smile We went through the same evolution to get to where we are at now as well. As for runner lengths and plenum size its all application specific. I'm sure if you saw what we have you would say it is junk and will never work smile
