That is the same cam I was trying to sell for my bud at the dealer, then ended up buying it for my build because the price was right. I am going to throw a degree wheel on when I set mine up and play with advancing it to see if I can shift the power back towards the bottom end. I really wanted a .390 cam but like I said the price was just too right to pass up.
According to the specs in that link it is a .440/.390. The only difference I see if correct is the lobe centers are different. My card says 110 degrees and the specs listed in that post for the WB cam says 106 lobe centers.
