WOW!!! Cool video Phil. Thanks for sharing...
Part of me wants to call BS on this one, but it’s hard to argue with a video... They did meet the requirements of the challenge, "sort of", though at least one component was obviously pre-disassembled, i.e. the hood. I’m sure many other items were previously “arranged/set” such as everything mechanical, fluid, and electrical that isn't required to "just start the engine", were all disconnected!
To fully DISconnect AND REconnect the following;
Fuel line, throttle linkage, exhaust, half shafts, shifter linkage, heater hoses, motor AND transaxle mounts, Dizzy primary wiring, starter wire, (not sure they bothered with alternator wiring, coolant and oil senders or if those components count in the challenge), coolant hoses, coolant drain and replenish, would add considerably to that time. Sure it drove 10 meters without coolant, but C’mon… that’s not “truly” changing an engine now is it? The 3.1 hours quoted by the commentator for a "garage" to do this feat takes into account fluids, electrical, mechanical connections not already being disconnected prior to starting the clock….
None the less, still an impressive display…
