Anyone know where I can find a new engine?

I need your help, I have to find a site or place where I can find an engine for my 1990 Chevy Lumina 2.5L, automatic. If you could help in with my ordeal, it would be great. Send me info if you know where.

I have a 3.1 engine for sale from a 94 lumina, body types are the same and minimal changes would be needed to install it.
