Being that Aero-nomics are of a different subject, I would agree that it is subject to being discussed here simply because of the aluminum sheeting used to make such air foils.
The drawing shows the backend of a typical 64'-65' early B-body. Underneath and in between the bumpers lower lip and the bottom of the trunk floor exist a body width long air pocket basin. Some of the traveling air gusts may find itself around such a catch basin, but for the most part, it will end up being turbulently tossed within that basin.
The chassis/frame longitudes and the fabricated air foil are high lighted in the darker ink to show how they correspond with each other and smoothly help deflect air once it is attached. I do not know how it would work with or against in a really fast car above 140 mph blasts.
Keep in mind that this foil is totally stealth once painted flat black unless you look hard underneath.

Maybe this coming season we can put my GoPro camera under the rear of your car and do something like the pic below to see what happens to the air under the back of the car at speed.

Makes you wonder what the difference is between a gas tank and fuel cell.

yeah, I forgets what kind of yarn the boys on the Missile program used, but a go-pro will record it live and show what's happening in real time.

What I did was re leave the outer areas of the rear valance in the outside corners to let air go THROUGH the car and I removed the cross piece of metal bet. the frame rails and torque boxes and behind the lic. plate for the same reasons. IF this doesn't get me the results I want then a few deflectors will hopefully finalize it........ luck

Yeah, some cats may laugh and send us to go knit a sweater, but the fact is, it worked then and will work now. But it does help to have a Go-pro and get a good view.

Like Cab told me years ago after I asked him how to get down the track and go as fast/quick as possible and he said quote; It's everything between the ft. and rear bumpers, so work on that" lol.............Been working between the "bumpers" ever since............ laugh2

I know this may sound like picking too much fruit from the tree at harvest, but I wish these buckle pieces could be made out of 6AL4V Titanium. They are understandably made from a good grade steel, but on the heavy side when you combine two sets per front of a car.
I probably would have fabricated a set or two already if it weren't for my fear of not being able restitch the lap belt folds with the proper stitch material or strength.

Old cars will always upstage the new where ever you may go.
Just ask the designers of certain modern retro-classics off the assembly line nowadays and the prop masters on the whole Fast and Furious franchise.

Exactly, and my reasoning for laughing at $80,000+ plastic modern "race cars" that all look alike in some respects and make gobs of power because they weight a ton..........no thankxx and who needs a/c in a hot rod any ways............ beer

Sorry for not posting for a while but I have not forgot the weight loss program for this spring! I have read from page 80 through 110 and will copy some work that I saw on my front drum spindles while I'm installing new light weight pads and rotors!
In my first pair of pictures you will see that I have dug out all my inside door handle pivots. The first picture shows the heavy one at 6.8oz and the second picture shows the light one at 6.5oz.
I will be able to shave even more off the light ones I picked out for each side!

Now I will share how this starts to add up!
My first picture shows a heavy pivot, heavy handle and longer bolt coming in at 10.9oz. The second picture shows a light pivot, light handle and shorter bolt coming in at 9.6oz. This is a savings of 1.3oz per side without any more mods to the parts!

Next I started digging around in my outside door handle box and came across a nice find. My 1970 GTX uses the chrome style push buttons. These weigh 1.2oz! Back in 1968 and early 1969 Chrysler used a plastic type push button. These are the same in every way except weight. The black plastic buttons only weigh .4oz for another savings of .8oz per side! My total so far for this spring is around 10 pounds!

MoparJohn where did you score that scale? I am also anxious to see your spindle pics as I just got my Wilwoods and I am hoping to find someone to trade me a set of A-body spindles to machine for my stock spindles once removed.

I purchased my scale initially for weighing small packages from my local post office. It weighs in a tenth of an ounce up to 10lbs!
The price was reasonable and I've used it a lot! Check with your local post office and if they can't help there are some on EBAY!
On the 10" B Body front drum spindles, the original poster basically cleaned them up and shaved several ounces off each side. I think it was close to a pound off the front!
