Does venting the front hood do anything?

You can answer that yourself. Measure the surface area of your radiator (width x height), then measure the surface area of the vents you like, and divide. Most vents will be only 10-30% of the radiator area, and are not fan- or even duct-fed. So by the laws of physics they cannot pass more than 10-30% of the air exhausting from the radiator (most of which will go out the wheelwells & under the car). Sure- when the car is moving above 30 mph, more air will be sucked out the hood vents, but few if any Panteras have heating problems above 30 mph. Conclusion- hood vents including '75-up factory types are mostly decorative.
IMHO, the ONLY vent that does anything at low AND high speeds is the giant GT 40-style vent, and to install one of those, you will be cutting 1/3 or more of the front trunk and front suspension supports away, which has its own problems. There are far less drastic solutions if you have minor heating issues. If you must vent your hood anyway, I suggest buying a fiberglas replica and cut that up. An intact steel front hood is worth around $1200; a cut hood is worthless.
