So before anybody starts in, I know that I can just go buy an aftermarket intake, but... I really want to have a car that nobody will be able to estimate, even with the hood open, so I was wondering if anybody has ever had their stock GT manifold ported and opened up a bit, and if so, was it significant enough to feel, or am I stuck with getting a Cobra GT-40 or Trickflow? I really want to know because it will decide whether or not I get my E7's ported or go for a Cobra Conversion.
