A500 in an Early A

Donno if you'll be able to find him, but Paul Pitcher ("Pigdoc" on the Mopar Mailing List ) put an A500 behind a 360 in a '66 Dart wagon. I drove it about 15 years ago when he came visiting Toronto and I lived there. This post contains a string to tug at about it, and maybe it's still possible to join the MML and get access to the archives.
