Something to keep in mind is that the BBD article doesn't talk about what ride height they measured the roll center at. Or at least as far as I can tell they didn't, maybe I missed it.

The article is pretty old, so I wouldn't be surprised if it was at a stock ride height. So, while they list a roll center, I would bet it isn't much use comparing them.

Not that you said you were, just an observation.

Also, I wonder how camber gain is affected by initial camber. They started with zero camber and it seems like the norm now is a half to one degree negative chamber for street cars.

This is very true.

I don't think static camber changes camber gain by any measurable amount. Obviously, more static negative camber shortens the UCA, but it is such a small amount, I doubt it is even measurable. My static is currently 1.7-1.8. I just started from zero to make it easier to understand.

So the Big Block Dart article is just a reprint of Bill Reilly's article that was originally published by Mopar Muscle. It's still available online here https://www.motortrend.com/how-to/mopp-0503-swapping-a-and-b-disc-brake-spindles/

Unfortunately, when Hot Rod and then Motor Trend brought all of those articles over from MM the way they're posted online doesn't capture all of the original captions under the photos, which is where they described the ride height of that car.

I do know, because I've posted it here before when the article was complete, that the car that provided the data for that article was lowered 1" from stock. I've tried to get most of those important articles in the original magazines, I'm not sure I have that one though.
