Engine pull question

<50 minutes for a clutch, on the ground, even for two guys, and without airtools; that's flippin'....... Fast! My hats off to you guys.
We were young and hyped up in 'racing mode'.... and we had a 45 minutes service window to beat! I think we took 2 minutes of penalty time....

And then there was the time with the header repair in the UP of Michigan.... LOL
