I'm usually up at NED once or twice a month, typically one friday, and the import events. I used to go wednesdays, but it is easier with my job to go fridays than in the middle of the week.
And, I had the stock cams on there for the 15.3 run, adjusted with cam gears. So, once I get the right aftermarket cams and they are finally installed, I should be able to drop that time a few tenths or so.
