Cobra motors had the cobra intake different valve covers and "3 bar" GT40 heads
People will try to tell you they have a cobra motor just by throwing a cobra intake and valve covers on it dont be fooled
you are better buying a short block and building somehting on your own
this is a cobra intake http://parts.factoryfive.com/Ford/pictures/14344.jpg
dont let people tell you its a cobra motor because it has that, the main thing to look for is the 3 bars on the front of the heads
