I think theres a good chance ported GT40 irons will flow more than the stock explorer can support. I guess it depends on how the poting goes and how much they flow after that, but I guess you know that already too.
Anyway, Im not disputing what intake will work best with his heads, but its clear we have a different definition of "virtually identical".
10 CFM, in my opinion, and many others Im sure, is not "virtually identical" when it comes to the world of airflow and manifolds and I thought kystang86 might be interested in this information before he decides to buy a explorer only to find out later it flows considerably less than the cobra.
I would let you slide on calling the cobra to the GT40 "virtually identical" being that they are around 1 cfm difference, but not the explorer to the cobra.
