Thanks Mike! They were probably only slightly heavier but couldn't be much different than a Bee or a Bird? I was kind of kidding but back in the day, I didn't run into too many Chargers who were interested in running. There was a Y4 R/T 440 with headers and ladder bars but he would never run anyone because he wanted to remain undefeated. If you don't race you can say you've never been beat! He was a nice guy and his car was beautiful. He just didn't want to hurt it or take a chance of getting caught. I did run a 68 Hemi Charger that had one of those overdrive units on it. He still can't believe that he was beat like that by a 383 Road Runner. I think those were the only two Chargers I ever ran into and I was on the street looking for runs every night in 1970 thru 72!
