Back in the late 90s when I was racing my 71 340 Duster (stock), I could run 14.0 all day at MG, but no 13.90s. I swore the car had 13.90s in it so I kept going back to MG week after week trying to get that 13.9 time slip but it would just never get any better than 14.0. So I drove it down to Cecil County one Friday night and ran 14.0 first pass and a 13.9something on the second pass. So is Cecil faster? Maybe, but not by much for me.
