Can Anyone ID this Distributor

[hotrod]

When I bought this distributor I was toild it was for an Olds 455 which it is not. Can anyone tell if it will fit a Pontiac or possibly a Buick? I'd like to sell it but want to make sure what it fits. Does anyone have the dimension from the bottom of where it sits in the block to the top of the gear for a Pontiac or Buick 455 or V6?

I was told its a Holley billet distributor but there are no numbers, markings etc.
