340 actual horsepower

I bought a nearly new 70 Swinger 340-4spd,3.55s in fall of 1970. The following summer I tracked it pure stock. They shoved me into F/S at 300 hp. She went 14.4@98 and change,still in third, Spinning those Polyglass E/70-14s, for what seemed like forever.
Got me a trophy that day! It was my first track day, and the last one for over 30 years.

Some folks don't realize all those ETs in the old magazines were off the showroom with some cars getting a performance tune. Most all ran with bias ply E-70 tires. Modern tire technology would propably knock .5 off.
