I just don't see the benefits. It seems like a plow through the air.
A design like Fred's would still direct the air around the car but be more aerodynamic. I suppose it depends on the race application too. A short track vs. a long track.
Homemade chin spoiler looking for some feed back please.

These cars lift dramatically at the front over 100 mph, the inset grille is a terrible aerodynamic design. That’s why the Charger 500 ditched it.
And it’s why the T/A and AAR cars got the large front spoilers, and it’s why the guys that vintage race these cars usually go even bigger on the front spoiler than the T/A and AAR cars did (ie, that challenger in my last post).
The basic principle is the less air that goes under the car the better. There’s always a trade off between downforce and drag, but because these cars lift at the front so much pretty much everyone that does high speed road courses runs a massive front spoiler.
The speed is the determining factor on whether you need one, like for AutoX the spoiler/wing stuff usually doesn’t help because the speed is usually sub 50 mph. But for a road course if you get up toward 100 the front spoiler on most muscle cars gets pretty darn big.
I have a little experience with epoxy casting. This is a mahogany pattern my dad made in his pattern shop. This pattern is for a aluminum sand casting. This is what patterns and models like like, you get the idea.
But,
This is a epoxy and fiberglass cloth casting taken from a model and was used to cut a cavity and core in steel on a duplicator milling machine for a plastic injection mold and castings of the parts in epoxy for checking size. This is for a prototype mold making fiberglass impregnated plastic safety shoe inserts that was made in the 80’s. The project never made past prototype faze as they had a hard time filling the mold with material and the abrasiveness of the fiberglass impregnated plastic washed out runners and the core in the mold rather quickly. I do not have the original models the impressions were taken from.
There are quite dirty as they have been on a shelf for 40 years.
That's cool and bet you could teach me a bunch. Thanks for sharing that. It's always nice to see what other members here do.
So I got an idea the work that went into your air dam. You did an awesome job with the “buck” and your air dam looks killer. Well worth the $300 your asking for them.
Thanks and yes lots of work but I am one to screw up and have to start over.
No, That was my dad’s and grandpa’s work. I’m not a pattern maker. I just know a bit from growing up around the pattern shop and helping out here and there. No way I’m even at your level.
Used to be you could buy a one piece fiberglass front end for a 68 dart. That company has went out of business I believe. $600 what a gift, wish I would have bought a couple. What a project making a buck that size. That is why I asked about shrink.

I’m no different, my dad was gifted. I have to fight every inch.Thanks and yes lots of work but I am one to screw up and have to start over.
My dad was the same and miss him lots.
Sorry to hear. My dad at 95 is at the tipping point soon. Not much left in front of the horse, most behind the cart.
I like that. No regrets

I wonder if that could be made to fit a 76. Anyone know how different the 73-74 bumper is from the 75-76?
I don't remember the 76 bumper but I think they used 5 MPH bumper brackets and if my memory is correct their round tubes.

agree with this ^^^^^^^^^^^^^^^^^

I bought this air dam 10 years ago on ebay for $75, the ad said it was for a 73 to 76 duster/dart but from the shape of it I thought it would work on my 72 duster. I did have to recess the center of the air dam to clear my license plate bump on the bumper but it turned out pretty nice I think. I can't tell you how many people ask where I got it or who made it, there were no markings or part numbers on it. I think $300 for yours is a good deal!
I dose look nice and the car is fantastic. I'm not sure but if the 72 doesn't have a lower valance I believe mine would fit.
Wish I could barrow some ones 72 car to try it out.

I'm impressed with your projects! I do have interest in you console for my '65 Barracuda with stock Hurst 4 speed. Could you make a console for it?
I could if I had a 65 to make a pattern with. Would be a fun project.

So I need to bring it up there and leave it for a while?
Shifter off the side shouldn't be a big problem but tight between the seats.
Takes a lot of work for me to build a center console but I enjoy the hobby.
Wish a picture was all I would need to make one.
This is how I did mine. Pictures are better than trying to explain how.
From cardboard to heavy insulation foam glued together.
Sand and shape it and I used bondo over that to get a nice smooth surface.
And ship it to me and I can finish it.

Well considering I'm not an inventor like you, by the time I made 4,329 molds, it would be cheaper for me to have someone like you make one and it would be better!
