ok guys, ive got a question here about a possible combo, its for my dad's 94 gt, the car already has a cam (seems like a 'b' cam or similar), full length headers, 2.5" h-pipe with high flow cats, 2 chamber flowmasters and a 3.73 gear, i dont think the stock intake is working very well with the cam, im sure the heads arnt helping either, but they are suposedly ported (car was like this when he got it) i can get a good deal on an edlebrock performer 5.0 upper and lower intake (not the rpm) and i want to know if this will be overkill for the setup, would something like a cobra or gt-40 be better, or are all 3 comparable, any help would be great, thanks
