looking for a good 273 or 318 with matching 904

Title says it all! I'm looking for a 273 or 318 with 904 transmission. Wanting to swap out the /6 for something with some grunt for my daily driver. I'm in the Athens-Clarke County, Georgia area, so somewhere close to here would be preferable.
Not looking to spend alot, maybe a couple hundred? I'm not apposed to a rebuildable engine either, as long as it's not to far gone.

Thanks for the ad. And if anyone has one they just want to give away, or get out of their garage, yard, etc, let me know!

Thanks again.
