If you had the $$$..... would you

Actually, the headlights and flat grill means it's a 88 or 89, 90-98 had composite one-piece headlights. also looks like 94-01 dodge dually rear fenders mounted on the front.
And, I'm pretty sure that although that windshield would probably help one's mpg's, it would dangerously decrease visibility where the front meets the sides and the cost of the custom 40-inch wipers would probably offset the fuel savings lol

Ill take it a step further.

I probably wouldnt pay a shop to do it.

Instead I would ask around to see if anyone
needs a side job and then barter for some/all of it.

I'd go with the skirts and roof extension. In (random)fact, why not go all out with the roof extension, with a hinge to allow trunk access? Also, an aggressive nose job would score points.



On the other hand, if you're mostly city driving, then weight reduction and reducing RR might be better.

Maybe something like this? I have one, the dash is like 3 feet long and not moveable, it is a royal pain to work on. Getting to the back of the engine requires laying on your belly and stuffing your head and arms back there, and I'm small too. If the engine ever goes, it would have to come out from the bottom.

On the truck in the original post, I wonder if the whole thing opens for engine access.

Your dash is longer than mine... and I have at least 2 feet from tip to windshield LOL.

There's this giant black panel in there that I thought about putting solar panels on, but the cost is still prohibitive.

The truck in the top picture is, I'm pretty sure, a screencap from the movie Tango and Cash.

Dumb movie. It did introduce the definition of the word "FUBAR" to everyone, however. So there's that.

Would I do that? Maybe, if I had the money. My truck is pretty upright, and a longer slope would open the hole in the air a bit more gradually. However, I wouldn't bother until I had already done a kammback to take full advantage of the smoother flow coming over and around the front.

A quote from Hot Rods article entitled " Wind Camp"
Concerning aero 'myths' -
" The biggie: windshield rake: According to Eaker, "Here's a myth I can bust. Once the windshield is past 45 degrees of rake-and many stock cars average like 60 degrees-you will not see an improvement from laying it down at an even steeper angle." We proved this on the Camaro, building a hugely sloped "windshield" out of foam core. It did nothing."

This quote comes from the guy that runs the A2 wind tunnel, and worked on the EV-1 aerodynamics.

( Am I the only one that would love to invite him over to our site ? )

Here is a link to the article : Car Aerodynamics - Hot Rod Magazine

BTW, Note that this is a several page article

Cd - you have to consider that they were testing a stock car with a naturally high Cd, though, and no airflow improvement at the rear. Obviously, any change to the windshield angle would not alone be the end-all be-all of aero, but would work as an aide to keeping the flow smooth over the top of the car and off the boat tail, if it existed.

What I'm saying is that there might be more of a gain if the car had other aero mods.

didnt they get down to a cd of like .20 or some awesomely low number?

the backside of those camaros looks pretty aero to me, especially thiers that looks like it has some rake to the whole car
