I suspect you'd see a marginal improvement. I don't recall the cobra's having alot of changes from a GT. Intake, TB, different Calibration, injectors, etc. They were like 240 hp. You'd need to change some other things to get big changes, but you'd need an intake too. I'd just start collecting parts myself. Get the intake, save for some heads, and a cam, and do it all at once. Why take it apart 5 times?

You could see about 15-20hp over stock. The cobra is pretty big compared to the stocker.

Actually there were quite a few differences:

Cast iron GT40 heads
Cast aluminum Cobra intake manifold
Crane 1.7 rocker arms
24lb fuel injectors
Cobra specific ECU (computer)
Engine oil cooler
Front mounted power steering fluid cooler
Lightened flywheel
Phosphate coated transmission gears
Overdriven waterpump pulley
Cobra specific camshaft: Duration: 227°/Intake & 270°/Exhaust Lift: .485/.485 Intake/Exhaust
Lobe separation: 118.5°

You'll definitely see some nice gains with the intake. Like wytstang said, it's pretty big compared to the stocker. If you have a factory strut tower brace, it will need to go, the cobra won't fit under it.
