Yup, yo are right, I must have been under the car too long smell ing
gasoline fumes. Regarding the thread my queston was when did the big Top
Fuel and Funny car motors get involved in it. I was reading all of the
messages then up pops one where Dave and John or somebody was nattering at
each other on the amount of hp to get down the track. Must have been one of
those messages that did not get the trailer deleted ...
very interesting stuff..
and thanks Elon
mayf, off planet, and apparently out of it, in Pahrump

5,000
> lbs/1 ft or 5,000 lbs/2 FT. Which is less? Elon
