Dart heart transplant soon

I’ve pumped in some numbers on those silly quarter mile calculators, and one says 11.07
The other says 10.56
I was thinking 11.0 maybe 10.9 with the 3.91 and a couple tenths quicker with optimum traction and the 4.56
Though the Challenger is almost a second slower with the 3.23 versus the 3.91
12.7 versus 11.90
Car always ran around 7.47-7.56 1/8 mile at about any track, with old engine.
