Hello Greg.

My scoop has the curved leading edge. It's taller, and wider than the standard scoop, but because it's wider, it sits on a lower portion of the hood, so the height of the scoop at the center of the hood is not that much different than that of the standard scoop.

Yes, those intakes are part of my collection of parts that at one time I fantasized about utilizing ! I believe there were only about 10-20 pairs of original weber 58mm downdrafts ever made, I think initially for Indy cars. Hilborn fabricated mechanical fuel injeciton throttle bodies to the 58mm weber intake.

So I've learned from Ned Scudder at SAAC that the original 289 race car hood scoops were aluminum.

But there were only 6 initial factory race cars growing to 32 cars in total over the Cobra's 3 year race history.

So aluminum may have made sense initially as the numbers were small.
And that might explain the wide variety of hood scoop configurations shown in period photos as they might have been hand-made aluminum , being replaced as necessary due to damages.

But as more Cobra race cars were added and later in the race history perhaps they switched to fiberglass and finalized on one configuration.

A configuration that was eventually handed down to the 427 Cobra in 1965.
Now the first production line 427 Cobra, CSX 3003, to come off the AC production line in Nov ’65 carried a hood bubble rather than a hood scoop:


Sure looks like that hood bubble was a carry-over from The Turd:


But by the time CSX3003 was finally completed at the Shelby Venice facility in May ’65 it carried a hood scoop similar to the later 289 race car hood scoops and looked to be fiberglass:


So where did that bubble hood go?

Could that hood be hanging on a wall somewhere?

Or was the bubble cut out of CSX 3003s original hood and then a fiberglass hood scoop added?

“You are traveling through another dimension, a dimension not only of sight and sound but of mind. A journey into a wondrous land whose boundaries are that of imagination.
Your next stop, the Twilight Zone.”

Cheers
Greg
