Cool video, nice ride for sure 4.66 @ 153 is very impressive 1/8th mile
not sure if it's the fastest "actual" leaf spring suspension Mopar or
the fastest 1/8th mile Mopar with stock "style" suspension
saying it's a leaf spring car with stock "maybe" attaching points, style of suspension...
It's quite Possibly is thou...
Most guys going that fast,
will go with coil overs {or with mono-leafs & bars like Calvert CalTracs even}
or even better yet a 4 link even a Ladder Bar set-up....
for the adjustability...
The F.a.s.t. Guys are really Impressive with their restrictive stock appearing rules
& stock-ish type tires & not slicks...

That is Jason Digbys dart. It is on leaf springs.
