crap t&t night

A few weeks ago...we had the 71 fuster out...and it had slowed a bit...60 ft were at 1.51 instead of 1.44...and et was off a good tenth....mph was pretty good...but we had a small tail wind..

I had just change a few things..like msd 6 to 7..new plugs...cap ..rotor...and changed carbs....but still ran the same.....someone said the air was at 5400...got my old TAG out and yeah.....Gpt the time slips out from April...and may..plugged them into the DA calculator..and corrected they were within a few hundreds of each other....
