Post your 10 second combo
I've been following this thread since the beginning. Partly because I have a big block Feather Duster and partly because the opening pic of the moparsofmn yellow duster at rock falls has my blue and white F150 in the background. I've raced at Rock Falls many times and have seen moparsofmn's car many times as well.
In Oct 2014 I ran 10.698 at 117.38 mph in cold air.
However, this year I have been only at the 1/8th mile track at Grove Creek Dragway in MN due to the low gears. We have been running fairly consistently over 25 passes in 80 degree heat.
60 ft 1.483
330ft 4.264
660ft 6.61
660 mph 105.84
According to Wallace racing calculators this equates to about a 10.5 1/4 mile
