Hey Lar, I had a 68 Charger that went 10.70's back in 2000. It was all steel, full interior, steelies, dog dishes and et streets, no cage and dynomax mufflers/exhaust. It had a 451 with Indy srs, 660 roller, 1090 king demon, 5200 converter and 4.56. Was not pump gas, but I drove it everywhere including to and from the track several times (70 miles ea way!). Best pass was a 10.70 at 126, but I did drop the exhaust for that one.

I also went 10.98 once in my old 65 Coronet wagon, but I wouldn't call it a 10 second car since it only happened once.
