I can only think of two 2-time Pro Stock Champions. One is real obvious as it is Jim Yates, so he is the one who is "currently racing who will have the major announcement" regarding his program. The other is Jeg Couglin, so it will be interesting to see if he is going to make a come back as the article alludes to.
EDIT: I can't believe I forgot about Alderman's 3rd title in original post. D'OH!
