Engines don't matter. It's the transmission & flexplate that matters. If they both have either a TH350,TH400, or Powerglide it will work. However, you will have to measure the flexplate bolt hole diameter to see if a different flexplate is needed.

Oh, and different diameter flexplates have a different number of starter gear teeth too.
