The best ones were functional in the 1960s early 70s
They had a butterfly that was controlled by engine vacuum and when going WOT
the butterfly would be opened all the way, allowing the marketing claim of "RAM AIR" and flowing colder air through the carb
Most of these were phonies with not flow into engine bay
The hood I had made for my C5
The openings by windshield would make use of low pressure and that colder air get sucked into engine bay
In the front openings, hot air raises and as car moving, the air stream pulls out that hot air
Hence, engine bay and all inside stay cooler
Even in rain water does not flow into engine bay and if washing C5 there is drain tubes on front ones where flows to the ground

Yes, you’ve posted a couple of pictures of it. What a car. Would stand tall against most if not everything on street drags. The only things that would be close or equal to it were the Chrysler 440 six packs or 426 hemi’s.
Bet you wish you’d kept it, but it those days it was just onto the next one. If only we knew.

Have a friend (not at the time) who bought one new. He worked for Ford in Detroit at the time, Hugh Ford employee discount. Was racing mad as a 20 year old. Some of the stories are great. Kept it until the first fuel crisis in 1973. Went from the 429 to a Ford Pinto because of the gas prices. Tho today he says he loved that little pinto

So, so many of the hipo cars ended-up in trees or lamposts with people who were unable to sensibly 'apply' the power.......got caught out myself once too..........
Perhaps the reason why I don't like muscle cars with auto transmissions........there's always a short delay between 'letting-off' the gas pedal and things slowing-off underneath......if only 'micro seconds' its enough to send the car off-road and out of control.

Case in point is the c3 LT1 hood over the base hood . Still looking for one by the way if any one stumbles across one

It was a fairly common upgrade back in the day to “upgrade “your hood. They were not that expensive new over the counter at your local Chevrolet dealer, and once the aftermarket guys started doing them even more so.
Now originals are big-ish money and aftermarket ones vary tremendously in price, and shipping is expensive especially for us in the UK plus things like taxes VAT.
Keep looking, hopefully you’re come across one.
