This is the GM factory Nitride Cross-Drilled sought after crank.
(Official Part Number / Description 3967811 Crank-427 0.646)

When Gordy first took a look at it over at Pfaff's he said it was one of the nicer ones he had seen out of the box.

Ran probably about 40 heats on it in my Super Stock.

After running it, during a motor freshen-up, it showed evidence of a crack while going through magna-flux.
If you came across it at the swap meet and gave it the "ring test" on the asphalt it would pass.

It is standard, however it has some scuffed journals and would have to be taken down. Not sure how much.

GM list is $816. I originally, through a friend's employee discount, paid $677.

Make me an offer. If it's decent we can talk.

There are those who say that literally every crank out there, which has been run in a motor, has some kind of microscopic cracks.

May be that there isn't a person in the world who would want it.

Then again there may be...
