A good home port will only give you about 170cfm intake on E7's. A far cry from the 190cfm on the GT-40/GT-40p. While technically a set of hogged out E7's machined, and CNC'd with bigger valves will outflow the GT-40/GT-40p's stock, it's not going to happen without MAJOR work. The E7's are limited to a max on the intake of about 220cfm.

Here's an idea. Go to Ebay, get a used Explorer or Cobra intake $200-$300 save a few hundred that way, and use that money to get a set of good used GT-40s. You'll have to get different headers with the GT-40p's, and that will add cost.
