9 seconds on 9 inches???

Wanting to build a 69 dart that runs highs 9 second to low 10 second quarter mile. It currently has 8 3/4 with s/s springs relocated inward and a pinion snubber 28x9 slicks on the rear. I love the small tire cars that run big numbers. Just not sure if that small of tire would put the power down and make it stick.
The car has an a&a trans with a brake also.
Should I ditch the s/s springs for caltracs??
No, go ladder bars or 4 link if you want a real suspension. Of course you can run those numbers on stock leaf springs but why spend the effort unless your racing a class that doesn't allow it.
