My friend got his N/a cobra dynoed he said and he claims he got 430 hp at the wheels. All he has done to it is valve springs and an F cam and a few other little thingies. He also said he ran a 12.3 with him driving and an 11.9 with a pro driving. This is all completely naturally aspirated no nitrous no blower no nothg !!! i dont beleive it.
