High 7's in the 1/8..how much weight and power??

The figures are crank horsepower, but real HP numbers, not "my buddy says he had 300hp and my car is faster so I must have 400hp" numbers.

People tend to throw horsepower numbers around like candy these days. So to put it in perspective I'll use one of my old rides as an example. It was an Aussie A-body Charger (3400-3500lb with me in it), it was a real street combo that made only 270rwhp but on the strip it went 12.7 at 107mph running pump fuel, street rubber (not drag radials) and full exhaust. Drove it there, ran the numbers, drove it home. Didn't put a spanner on it.
