RE: gt40 upper/lower intake?
well the gt40 is not restrictive. it's my favorite intake. i am using the same setup you just said.... edelbrock performer 5.0's and gt40 intake. ported exhaust, cleaned up intakes, comp valve job, and lower is matched to the heads
some will say the 40 is outdated and others flow better, but i disagree.
$600 is a fair price but check these ones out... http://detroit.craigslist.org/pts/673330860.html
i wouldn't use the stock intake though, at least do a cobra or something, you don't wanna have to do the intake again later, and the gt40 lower gives you some good options. ike a breadbox from downs or cobra or real tubular.
stock cam, just heads and intake swap + 80 shot of nitrous i'm expecting to make about375 at the crank, or enuff to dip into the 11's
my buddy did it same setup, heavier car, similar portwork on iron heads, and 125 dry kit.

RE: gt40 upper/lower intake?
Is it the tubular one. I have it and its not that its restrictive its that it has restrictions. Basically if you are pushing close to 400 horse than it is restrictive. What you are using it for is perfect, its not one to be used with a power adder. The restrictive part is the lower, I mildly ported mine. The other reason they say the upper is restrictive is cause it can't be ported. You will be fine with it.
