Sum,  your truck appears to be a 38.  I think the 38 and 39 are the same.  But a friend of mine says the 39 has more convex shape than yours appears to have in the photo.

Your liner is looking good... My project is going ok... just some slow downs getting needed parts... but we are ready  to mock up the cage this week...

Keep up the good work.. I will see you at Maxton in May? (if your plans don't change)

Here you can see the difference in the grills (center vertical bar/bars).  I've seen the one on the left called a 38 and a 39 and the same with the one on the right.  I don't know if they had anything like the cars where they had the standards and the deluxe's that could look like one year or the other or not??

I'm planning on May.  It will be good to meet you and many others,

Thanks all for the replies,

now its much clearer. So its measured over a mile and the qualifing mile
must be the same as the record mile. Any of wich they are.

BUT what exactly is the 2 to 2 1/4 measuring for ?

Best ,

You have to run over 175 mph from the  2 mile to the 2-1/4 mile to qualify to run on the long course.

Also a good indicator of acceleration in the last 3/4 mile.

............ and it helps us on the 5 mile course as a reference point going into the measured miles.  We find that any thing we can pickup by the 2 1/4 is usually carried all the way to the exit of the 5.  Not sure that is clear so if we run 210 at the 2 1/4 and 236 exit speed at the mile on one run and then can manage to run 214 at the 2 1/4 on another run (4 mph faster) our exit speed will now most likely be 4 mph faster and be 240.  So we work on trying to get the speed at the 2 1/4 as fast as possible.  If you are still accelerating in the last mile you need to work on getting to the 2 1/2 at a higher speed.

c ya,

This has been a very informative thread. I always knew the speed was a measured mile, but didn't know about the 2 to 2-1/4 nor the repeat run having to be timed in the same mile.

Interesting, I learned a lot here.
