real easy question. i have a 94 gt and i found a 95 cobra upper manifold. will it fit my lower manifold? and how much of a hp gain am i lookin at?

r.barn

you might need the GT40 lower intake to make that Cobra upper work.

probably get 10-15hp extra

I would say around 230.

You will need a GT40 lower for it to bolt up. Ebay is your friend I got a 97 Mountaineer upper [$37 shipped] and a true GT40 lower [$125 shipped] and a plethera (<--3 Amigos) of other parts there.

EDIT: I'd guess around 220 rwhp depending on whether you need a good tune or not...maybe a little more.
