Yeah, they had Chrysler fully behind them and the Vegas and Pintos up front with their small block rules.
Apollo Trick Titanium was in heat back then to make a name for themselves in racing.
I visited their Troy location back in the early 90's and saw a trove of pictures from their projects with Chrysler. Wish I could have bought those instead of the fasteners. LOL.

As far as Chrysler's skunk works, the Wire car can honestly be considered their lightest in factory project yet. That titanium and Magnesium Dana is out of this real world.
I know that Chevy was slightly behind the "Black Widow" car back in the 50's and that car was tricked out as well.
There's a great little read by the name of "Cheating" about the Stock car circuit and their back door antics.
There's a lot to be learned by both the stock car and Formula 1 garages, but a bit pricey.
