Any 12 second combos with 3.23s?

I went 13.30's consistently with 3.23 gears and a 28 inch tall tire. I had a mild 360 (340 cam, J heads, .030 over 9 to 1, LD340 intake, 750 dp), 727 auto with a 10 inch street fighter, car weighed approx. 3250 lbs by itself. Drove it 1hr to the strip, and raced it 100% as I drove it. I would think 26 inch tires and better cam would have put me in the 12's, keeping the 3.23's.
