It all suggests you're losing something in middle of run.

So find what's off in the middle of your run and chances are you'll go more mph with a 7.0 or better et.
Looking at all 3 numbers I'd be looking for fuel issues mid range.

I was thinking that my 60 ft time was a little too good to be running 7.30's and not any quicker. I will try to run a good datalog to see exactly where my AFR is in the middle of the run. I have noticed that it doesn't feel like it pulls quite as hard as it should when it goes into 2nd gear. Maybe it's getting too much fuel. I'm at 37 degrees of timing now and wondering if bumping it up a few degrees would make more power as well, since I have the 87cc E Heads
