I think it really depends on the bell housing bolt pattern. I'm not familiar with a 313 V-8 but the bellhousing pattern may be the same as the first gen Hemis.. There are adapter plates sold to mate the Hemis with newer transmissions. There are a few old school companies that make them. A phone call or email may set you up.

I think Allpar has a large chart that defines the bolt patterns for most of the Chrysler engines.

Honestly, because you are considering a different trans, I'd seriously look into an overdrive unit. Dakota or Jeep ax15?
