Will This Run In The 15s ?

In the lightweight-A, I'd be inclined to guess low 15s .
At 3100# race weight and 235crank hp, that factors to 235/3100=.076-P/W and the book says 13.5 seconds with unlimited suspension. With your chassis, a high 14 second run might even be doable.But that stock TC and those 2.76s are really gonna strangle it.
I had a stock 71 Demon that had went 15.9@ like 79mph,when new, IIRC. It was probably at close to 3400 raceweight tho. Those numbers seem to be pretty accurate. 300 to 400 pounds makes a huge difference.
