What is the CRAZIEST thing you have done in a week to make a race

About the craziest thing I did in a hotel parking lot was on vacation in Ocean Ciry Md. I had built a very nice 360 engine for my used to be 318 tow vehicle. It started chattering with a couple of noisy lifters on the way down so I nursed it the last 30 miles or so. I had a few tools so I stopped and ordered 3 lifters by the hotel and picked them and a long magnet rod. My parking spot was under the hotel luckily so I was in the shade and with the 340 heads on it I was able to put the bad lifters and flip them over to were they would come out of the head. I could feel two soft ones on the driver side so I changed the two out. It took about and hour total after I removed the van doghouse. Thank God I was skinny back then
