Getting ready for the Mopar Nats @ E-Town

Getting the Dart ready for the Mopar Nats @ Englishtown Raceway Park in NJ
today. Checked "the" belt, hoses, fluids, wires, Torqued the lugs, and general inspection. All seem good.
Last time out I picked up on my 60", 1/8th mile and ET. But didn't have as great a gain in the 1/4 as in my 60's and 1/8.
My timming was at about 37.5* I just reset it to 35*.
Then I restriped the street I live on! :) .
I figured I would take a time trial next Saturday @ the Nats as is, and then bring the timing to 36* Take another time trial then decide whether or not to bring it back to 37*. A lower "all in" timing should give me more top end.
What do you guys think?
