What will my 68 Dart 408 run in 1/4 mile?

I only got to run it 5 times (was also my first time drag racing a RWD car) but it ran a 12.8 @ 106 with a 1.9 60 foot. I had been having trouble getting it to hookup so for that run I had loaded it up with a full tank of fuel, chairs, tools, cooler full of ice/food, and whatever else I could throw in the trunk. I launched at 3k and it finally hooked but bogged a couple hundred rpm.

I think different tires (currently running a bias ply sportsman pro 28x12.5), better gearing (installing 4.10 and ditching my 3.55's), and a new clutch that isn't slipping will help me immensely as I know I left a ton on the table with those runs. Previous runs I was hitting 110 mph but getting 2.1 to 2.2 60' times :/.

I had taken it to a local track for a test and tune day on October 6th (final one of the year) but it got rained out so I never got to run it again.
