Yes Chevy 6" with 2.1 BE There are chevy 6" with 2.0 BE but these are less common and therefore usually more expensive but would allow the 84mm out of a 6L crank.
Given the forgings only save you £200 at the machine shop as opposed to having a billet crank machined and you also have no risk with a machine shop supplied billet, no import taxes or carriage + insurance + agro of getting the crank to the machine shop, they are not worth the risk, The figures do not add up , which is why there are plenty sitting about. I dont know of anyone anywhere who has every got one machined up.

how much do they weight each...?
and should they be bead blasted to clean them up before starting to machine them...?
have they had anyone local buy and have one machined and if so who do they recommend to do this work?
I try to think of some more...

and a heisler steam locomotive does have a crank shaft and is a popular engine to show off ones prowess in the hobby...
and as home cad cam develops you will see more complex projects
the XJ13 for example... I expect that in the future some one will take the down loadable drawing of the car and put it into their computer and simply use it with a computer controlled plasma cutter and then just weld and pop rivet it together...
Sweet... and in time and smaller scale CNC machine for hobbyist that you could even make your own Kurbelwelle...

Did you ever have a chance to ask your friend the vendor about machining these 84mm cranks?
