Where can I buy a reliable remanufactured 318 for 1971 Duster?

I wouldn't buy a motor from CME if they were the last place on earth. I called them first when I needed a 4.7 for my Dakota, because they are close enough to go pick it up. Every single person I spoke with that day on the phone had the shittiest attitude that could be. The sales guy wasn't the least bit interested in selling me a 4.7. CME can go F a rolling donut! However, I am glad someone had a good experience with them.
