Mystery bracket ID

[Rixls6]

I got this bracket with a Big Block Chevy engine I just bought. Can anyone ID it for me? http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif The part number on the tag reads: 3878236.

Thanks

Wow, That was fast. Thanks. That makes sense. There's another bracket here also, but I can't read the number on the tag very well.
