Finding 360 engine/tranny to replace slant six

Thanks for the reply 67Dart273. I'm really interested in any 360, not partial to LA or Magnum and don't really care if it's EFI or not. Specifically, I'd like the swap to be as seamless as possible. So it sounds like I'll probably want to look for an LA (not magnum) that is carbureted (not EFI). Are all LA engines carbureted? Any idea what model year is the cutoff?

Sounds like my best bet is to try and find an older (80's model ?) 360 LA connected to an automatic 727 torqueflite transmission in an old truck or van. Did they put the 727 auto on trucks and vans?
