I'd like your thoughts on this 360

Ima thinkin' tire technology cuz those Polyglass tires spun thru 2 and sometimes 3 gears. I lived at the Southend of Winnipeg, in a place called St Norbert. In the late 60s the government built a huge diversion ditch to re-route the RedRiver around the city, to stop the annual spring flooding . About a half a mile South of us they build a big ol' dam to control the system. At the top of the dam was a 2-way concrete dead-flat roadway. And you guessed it; AJ used to go lay stripes across it with the 4-gear 340, and try to find the shifts in the tracks. The road was long enough to get into third with the 3.55s, before coming off the ends onto gravel. Never could find the shifts.....
PolyGlass tires, were better than any other street tires in 1970 , but they were like riding on ball bearings. E's were 7.35inches of tiretread, so maybe like 195s or 205s at most.Changing lanes in traffic could be tricky. Imagine 205s on a 340 today; what a crazy idea.
So 14.4 wasn't all that terrible considering she was spinning for something like 9 seconds.
