The reason that I’m thinking about a hood scoop is I want to put a spacer under my carburetor. I have a Edelbrock air gap intake manifold with a 750 Holley carb. and that will not clear the hood, Or it will be very close to touching the hood.
On the Street?
Forget the spacer.
You'll never measure a difference in first gear, and probably never below 65 mph either.
I ran a 750DP on the AG on my 367 on the 70 Duster K in my 68 Barracuda;
with a factory air cleaner from a 69 Barracuda. It did not rub, even with a .25 insulator I installed for insurance against percolation. Just make sure your carb stud is as short as possible.
Eventually I did cut a hole in my hood, sealed it to the carb, and mounted an oval Mr-Gasket aluminum filter housing to the hood, between the strakes. This to get fresh air straight down the airhorn. Was it worth it? Oh yeah, it spins the tires at least 20 mph further now,lol.
