Whats left after HCI?
The first thing that I see isn't your lack of power, it's that 1.79 60 ft. That's what I'd concentrate on. Which your new 9" and stall will go along way, but in the end with a auto at your power level it's all in the 60'. Your power level should easily give you a 60' in the 1.5s and that's mid to low 11s.
My car consistently runs 11s with a 1.58 60' with 321whp. I'm not even full bolt ons. That's with a stock ls1 intake. Others on here have gone faster. I am however full suspension with a lot of time spent on shock settings, pinion angle, lca angle, etc.
But if you look at any of the NA auto cars that put down lower ets than you think they should, take a look at their 60 ft time. They're all dialed in.
Trust me, it's a blast to line up beside a cobra with pulleys putting down 600 whp and cut a .010 light with a 1.5x 60' while they cut a 60 in the 2.0 range. I've outran more than one car in the 8th mile that way... you can make a little money because no one expects you to outrun their 600 whp car. Never mind their stock suspension and clutch!
