Let’s hear a 340 story

Keystone Raceway Park,My days there were mid 60's thru late 70's.
In the 70's I had a 70 340 4 speed Duster with 5.13's as my street car. Never made it to the track with that one. I was off to tec school in Denver.Sold the 340 and installed a 318 and 2.94 gears and headed to Denver.Took 3.91's in the trunk and swapped them when I got there.Race at Bandimere somewhere in the 15's on the weekends.
