Point of information:
The Wallace online calculator, which is the only such online drag racing source for performance figures arrived at by entering weight and horsepower numbers I know of, says a 3,170-pound vehicle (that's a 3,000-pound A Body plus a driver weight of an NHRA-mandated 170 pounds,) with 250 horsepower should turn in a quarter mile performance of 13.58 at 98.52 mph.
That's their opinion, not necessarily mine, but it's all I have to go on.
