Were there vacuum / diaphram type actuators on these doors??

If the doors came open,,I would think the scoop opening must have been too small then. That would take ALOT of vacuum,,,

The hinged scoop, was angled down, from top plate towards bottom, -- allowed the scoop to open at wide open throttle, and very slow speeds. As the speed increased, the doors closed by gravity and were pressurized by velocity -- interesting but marginal effective. Like the blow-doors on a jet fighter.

Thanks everyone for all of the information. Lots of great input.

Based just on cool air, I am going seal up my scoop. I plan to use an air cleaner, using the base of the air cleaner to mount the air pan. Worst case, I can always take it off.

If I can, I will devise in a monometer to measure the actual pressure in the sealed portion of the air pan.

Thanks again, John

Designed and made a posterboard mock-up/template. Will fit it up this weekend to the hood, and then use template to make up the air pan.

I went to a tapered side design to give more access around the underside near the carb. And, give more airflow room around the air cleaner.

Looks neat. DO you have a foam seal on the bottom of the hood?

no foam

I found a stop sign and made a handle to bolt it down on the carb stud

with my stage 4 heads M1 two inch adapter and 1050 it was even/ flush with the sixpack hood

at the time was running 11.00s ,with the airpan went 10.85 123 mph


this was 10 years ago cant use it with the indy heads I have now



it was free and it got me a 10.85 pass

Poster board & card board is what I use to make all my templates from also. Fewer mistakes that way.
I just saw where Tuff Paw is making scoop trays now. Might be a good place to buy from or get some good ideas.

I used 2x2" air conditioner sealing foam from the local hardware to seal mine but Moroso has a foam kit that I believe is 1 3/4" thick by about 4" wide and maybe 2-3' long you can buy and trim to fit

416 stroker from Nick at Compu-flow. 11.14 in full street trim. Seems like a new best every time out.
11.06 open headers----so far!!

My 6pak scoop is only 3" tall and the carb air horns are close but I still get a half tenth out of sealing it. My pan is huge like Stroker Scamps.
