727 poly engine transmission

Ouch! Think I opened Pandora's box when I resurrected this thread! All I wanted to know was if an LA (other than the '64-'66 273) or Magnum engine would bolt up to a '66 A engine (318 poly) automatic transmission. Got my answer, so it's all good.

I think it will. I was incorrect about the dowel pins. The early hemi is what is different. My apologies.
