Just wondering if anyone knows how much an L6 crankshaft weighs ?

Cheers

I don't have exact numbers, but I remember that when I lifted mine I discovered that it weights a lot more than I expected it would.

Just a WAG... but I would say in the range of 50 - 75 lbs.

Could be less, I am not all that strong.

You'r close Walter, L-28 cranks are from 46 to 48 lbs.

I find that a good place to estimate weights like this is the MSA catalog. While they don't seem to sell just a crankshaft they do sell a complete kit with a stroker crankshaft, pistons, connecting rods, etc. that they list at 70 pounds shipping weight (and a mere $1799):
