My "new" '74 Duster- or why I need a project like a hole in the head

I'm pretty sure for any road or autocross, those 13" rotors will stop with my 14.25" rotors. I do have a Hydroboost as well. A couple of other things to consider with our builds. I'm a little bit older than you and this was my last build. I was green lighted by the boss to do whatever I wanted to do. I assembled this car in my little 20x22 garage over about 2 years of weekends. I did use your Duster as inspiration, just kind of when all in, and added the warmed over 6.1 Hemi, EFISource Goldbox, American Autowire harness, Vintage A/C kit with my own design Sanden 7176 brackets seen above, a Passion 5-speed, flawless body work by a friend in Conroe, TX that is now deceased, rolled all four fenders for clearance, a 67 B-Body rear so I can run modern offset wheels, and the modern Challenger gas cap along with a murdered out triple black V24 rendition.

The car can be driven (like you!), drag raced, abused on an autocross and when I become a better driver (autocross forces you to become a better driver than most couldn't comprehend) on a road course. My goal was to make it look tasteful, and as stock as possible inside and out. I also apologize and don't mean to hijack the best thread on building a tossable A-Body anywhere!

Not highjacking at all, heck your build (and others) may influence the next version of my own build! I've got a modern challenger fuel door, quarter section and filler neck sitting in my storage unit somewhere, waiting for me to do bodywork. Been there a few years now. And I am strongly considering the GIII hemi route, when my shop is done and my major expenditures on it are finished I may have to call up @Johnny Mac over at BluePrint and talk about their ~600hp GIII. Should bolt right up to my T56 (there's a dangerous statement) and I've already rewired the whole car with the American Autowire kit so I have plenty of circuits. Regardless the car will go EFI at some point, dragging my 750 holley double pumper through 3,500 ft of elevation change for my commute, plus the significantly larger temperature swings I get doing that is a little tedious. I mean it's fine but man it would be easier not to have to change the jets every time the season changes.

I've also looked into the EPAS units, I like my 16:1 manual steering but for serious AutoX it might actually slow my ability to crank the wheel around. An EPAS and a 1.5:1 steering quickener to drop down to 12:1 might be the ticket.

My brakes are manual too, I think that's fine especially with the caliper upgrade. I wouldn't be too sure about the 14.25" and 13" rotors being similar for stopping though, that's an 11% increase in stopping power with the larger rotors. What pads are you running with your Viper calipers? I'm still just rocking the OE set that was in the calipers when I bought them, looking to get something matching or similar between the Viper front calipers and the Cobra rears.


No no no say it isn’t so. You can’t do that. Your car is iconic (at least on fabo) in my mind, and painting it would take away a certain aspect of its coolness. Your car is another one of my favorites.

I mean, I wouldn't get too excited about it. A quick trip through my photo album says my car has been black and tan for almost 9 years now. Good grief I can't believe its been that long already.

This was just supposed to be a /6 commuter while I worked on replacing half the chassis on my rusty *** Challenger! :rofl:
