The day of the 28th and the day of the 29th, thats 16+ hours. I turn wrenches, do exhaust, and fix cars all day, this is a cake walk. The shop is closed on the weekends, so I do stuff there. I know everything I have to do, have access to a shop, exhaust machine, all my tools, air compressors, welders, and emissions dyno with gas analyser(I can load the motor to tune it, and i have a wideband 7 channel datalogger in my car if I want to tune it on the street). I've got it covered.
