Holley 600 or 650 carb

[Kevin 1G Drummer]

I know this isn't really the best place to search for something like this, but I know there's a few hot rod guys here, and people who know people.

So the carb on my truck is a pile of shit and I'm looking for something to replace it. I'd prefer a 650 double pumper, but I'd also take a 600. I'd prefer a Holley but I'm open to other kinds, just no Edelbrock or Demon please.
