John looked like a great run especially on street tires and I think the run in the hill country was good for your Stroker

I agree because you have a hi torque engine and you are blasting the tires in all of first gear and part of second...the 60 foot is a sure sign that you are spinning AND you are also losing track position in the 1st 1/8 mile because of it. Your can has a bunch more ET in it if you can get it to stick for the first 100 feet.
