This is the actual motor before it was customized. That carburetor was the one Mopar was experimenting with for production.

It's thought to be the very first use of a Thermo-quad on an engine slated for a factory production line Mopar. Sharp eyes will see that not only is it a Thermo-Quad, it's a Competition Series TQ, the very first TQ design which was only sold over the counter at the time. Sadly, we may never know much more about which carb it was (850 or 1000cfm, or 1969 or 1970 version) because Arruzza got rid of it. Also notice that the minty fresh NOS alternator it's wearing was replaced with a generic version.
