LOL All of you have got to be kidding regarding POWRi engine rules. All of you must be naive. When was the first time or anytime you saw, heard of or witnessed an engine being checked at a POWRi show? For starters, IOWheelers, one famous factory backed engine USAC midget team that has won multiple POWRi shows this season brings a totally different package than to a USAC show. Compare the pics..... What you think you see is not really what you think it is........
