5ohpatrol is right on the intake, the Holley is a great intake. The only thing that I feel you need to look at is the matching of the system. Basicly when does the cam tell the engine when it needs shifted ? The cam I have now is a high rpm cam. It wouldn't work to well if I tried to spin 7500 rpm with a Gt-40 style intake. Thats where the Holley helps out. If I had an engine that I shifted at 6000 rpm, I would try the Cobra out first, especially if its a street car, you will love the low end torque that it will produce. I have friends who run 10.60's with the cobra. My self, in the sig, that was done with a ported lower and a GT-40 intake shifting at 5800 rpm.
