390 or 360?
I picked up a block and told it was a 360. The only identifying marks I can find on the crank are a "2AU" and the number 41. I had heard that the 360 has a large "U" shape out of the rear flange but this crank only has a small notch, about 3/8" square. Any ideas? Thanks for the help.

Well, after searching through and reading some of the other posts here it looks like I may have gotten lucky and picked up a 390. $50 for the motor and tranny ain't too awful bad, doesn't appear to have ever been punched out so I'm in hog heaven, out with Windsor and in with the big dog.

I'm surpirsed nobody has helped ID the crank. I don't know the numbers well enough. Just measure the stroke, 3.78" is a 390, 3.5" is a 360.
$50, that's discusting! I've paid more for a bolt kit :-)

2UA is indeed a 390 crank. $50 ain't a bad price either, but I have done better, I stopped by a local auto machine shop the other day and while talking to the guy who runs it, he found that I was interested in FE motors. He gave me a std/std 390 crank, a set of C8AE-B rods & std flattop pistons, and a set of C8AE-H heads. It turns out I later needed two of those pistons in overhauling the 390 in my 68 Monterey. I've now got part & pieces of 4 390's in my shop and I don't think I've got more than $100 in them.
