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

I have two that should have put me in the "crazy house." One was 24 hours and one was technically 5 days. Back in the mid 1980's I was going rounds but the car was slowing every pass so I kept bumping my dial-in up .10 every round. I lost in the final and took home some money on a late Sunday afternoon. I unloaded the car when I got home and did a quick leak-down on the engine and found issues on both 4 and 6 cylinders so I pulled the intake and head. Back then I was running 9.80-10.0 in the 1/4 with stock crank, stock re-done rods, TRW high compression junk pistons, and 906 heads in my Duster. Well as luck would have it I torched a head gasket between the cylinders and ate into the block and head a little over .100 so that ended Sunday nights work. During my 8 hour work shift the next day in the mill I lines up a couple of welders to see if it was repairable. Both said no being cast iron. Now remember this was 1985. At work the next day a heard about a guy 25 miles from my house so I called him and he said bring it out, so I did Tuesday night. Now remember the engine is in the car so I took fiberglass cloth and a material we called KAYOWOOL in the mill and used it around furnaces so I could protect the cylinders while he welded. This guy looked like a Hippy from the 1960's and was one of the nicest guys you could ever meet. He looked at it and said heck ya he could weld it (in the car) but asked how I could get it machined. I told he I did Millwright work in a steel mill and we did patch work with grinders and files all the time so he said ok. I asked how much and he said 125.00 for both the head and block and then asked what the tolerance was and I told him I would aim for under .003 or LESS. He told me to call him the next day (Wednesday) and he would see how far he was and give an update. I called after 2:30 and he said it was done so after work I headed on up. Once there I checked it out and it was not only welded but he ground and filed it to UNDER .003. I asked what's up with that and he laughed and said he couldn't believe it could be done and then told me he only wanted 100.00 (25.00 less) because he was turning down jobs he would now take on. Luckily I happened to notice his beer brand and grabbed him a case on the way there. I thanked him and was on my way. I unloaded when I got home so I could start fresh on Thursday after work. Well Thursday I put it back together, fired it up, loaded it up, went to bed before midnight to get rested up for work Friday. Friday night it not only ran GREAT but I made it to the 5th round and got some valuable points. Now that would take me 2 PLUS weeks to do. LOL
