I narrowed the 4x4 wheel base to get it to fit better under the body. I also dropped the body by a few inches.
Stop in for a cup of coffee

I like it - again though, cowl hood and blacked out chrome.. but that's just me

First time at the new construction rodeo? Wait until you see the permit and inspection process for what you actually build...

What's with the blacked-out chrome bit? Did you have a bad experience with large shiny objects when you were a child?

Yep, I took out the lens warping.

- I just think it looks sinister
Yep. Thankfully a family (cousin) member happens to be the building inspector and hes gonna help walk me thru everything. Plus my grandfather was the county assessor as well as the township trustee for over 30 years before giving it up. So I'm not super worried about it. Kathy gave me the full list of the steps today so i can start planning accordingly. As much as you all think I'm dumb, I do my homework on most big items intensively.
It's the little stuff I screw up

not dumb - maybe a little impetuous sometimes

And don't get me started on aftermarket cowl induction hoods. They don't induct anything and are actually heat extractors that negatively impact performance by pulling hot air into the carb(s). They are the worst possible scooped hood you can choose unless all you want is the look.
Yeah I could see that lol. It's weird, something's I just say the hell with it and run with it but the bigger stuff I do tend to thoroughly research.

Not dumb, just inexperienced in certain things. But everyone has to go through it the first time in order to learn.

You want the dissertation on the aerodynamics?

Ok...here you go.
Cowl induction has been used since the early days of Grand Prix racing in 1910. This method is a proven, if a somewhat quirky and antiquated way to make horsepower. Cowl induction hoods use a backward-facing scoop in the hood to draw in some of the cool, high-pressure air that collects on the windshield at speed. Though a properly engineered cowl-induction system looks good and works well, aftermarket hoods with large cowl induction scoops can actually work in reverse and negatively impact performance.
The well designed cowl induction hood is sealed to the intake so that the low pressure created by the engine pulling air is fed by the high pressure air at the base of the windshield. They are they are generally no more than an inch or two in height so that they don't disrupt the dynamic airflow over the hood and windshield to stay well within the high pressure zone.
However, aftermarket large cowl induction hoods that rise above the high pressure zone (and aren't sealed to the intake) actually create a low pressure zone behind them that acts to extract air rather than induct it. This causes the hot air from the front of the engine (from the hot radiator) to be pulled up and across the intake and where it is ingested by the engine, adversely impacting performance. The pressurized air through the grille and up under the car is pushed upwards toward the low pressure relief cavity provided by the rearward facing scoop.
While a well designed cowl induction hood is functional, it doesn't provide any advantage over a forward facing hood scoop in terms of total pressure applied to the intake. Further, the forward facing scoop hood will never reverse flow no matter how high they rise. In fact, this is why top-fuel drag cars use forward facing tunnel ram scoops to take full advantage of the dynamic air pressure that occurs at speed. At 100 mph, dynamic air pressure provides 0.5 lb of boost if it is sealed to the intake. At 200 mph, it becomes around 1.7 lb of boost.
Many of the aftermarket cowl induction hoods are chosen to provide clearance for high rise intakes, superchargers and dual-quad configurations of the engine...but they are actually acting negatively for the total performance of the engine because of that same clearance...making the hood act as an extractor rather than an inductor.
This is also the reason why Mopar never used a cowl induction hood...even on the legendary 426 Hemi.

And you can see here that the Mopar engineers chose a large forward facing hood scoop for the iconic Hemi Dart that took total dominance of drag racing back in the day...

Aaaaand...I'm alone in here once again.
Oh well, I'm installing the new wheels and tires on the GTS tomorrow so it's time for some Friday night pizza and then bed...

First....
One of the guys in my group at work won $400 at the casino yesterday and bought us pizza for lunch/dinner tonight...
Yay!!!
@ScampMike see I now have another reason to hate cowl induction hoods other than being a chebby thing
