350 hp out of a fairly stock 340

Back in the fall of 1970, I purchased a lightly-used, low-mileage, run of the mill Swinger340/4spd/3.55s. The following summer, it ran 14.4@98mph, in pure-stock class, on the stock E70-14s, flaming them a good way out; it was a one of one run. I was happy. Ima guessing the mileage was in the range of 12,000 to less than 14,000.
The car scaled at 3310 pounds with me in it and about a half a tank of gas. IIRC the track was at ~800ft
The Wallace calculator makes that out to be ~240 hp. Like I said "run of the mill". But, on the street from 30 to 85 mph, it beat all comers. But I could feel the power nose over at about 85mph; which was ~5800 in third gear. If someone wanted to race to 100, I passed. I worked with what I had.
