Engine pull question

I and one guy R&R'd a clutch in the service area (pits) of a rally in north GA in <50 minutes. Included the time to pull the tools, jack up the car, R&R driveshaft, trans, bellhousing and p-plate, pull & re-attach/adjust shifter/linkage, align clutch (by eye.. yes, I am that good at it...), re-fill fluid, drop car, everything.... literally 48-49 minutes from pulling in to driving out. We knew the car that well.... so I won't call bull on some pretty short times..... with the tools and experience, you can do some pretty quick stuff.
That was the spring I tried to run synthetic in the trans. That trans was out and in about 5 times in two weeks, for modding.It wasn't having the synthetic no-how. In the end I slick-shifted second and third, and put 50/50 in it, and badaboom; shifts like lightning even at 7200. Just try to find a break in the blackies,lol. The trans, by this time, was all aluminum except the front retainer,with the Passon Aluminum case and sidecover, and the aluminum GV adapter; so it weighed less than 100 pounds with fluid in it. The 17 minutes was on a 4-poster with all the tools pre-selected and still on the cart from the previous pull. It was a Saturday morning.I think that mightabin 2004/2005. I was probably 51/52 years old, and strong as heck; That trans was nothing to throw back up; course I cheated a bit with a pair of line-up pins.

<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.
