I have a 66 Dodge Dart with an automatic transmission here in central Florida and I was thinking of pulling the engine to swap in a V8 but I wasn't going to do it anytime real soon, but I could. How soon are you looking to get a hold of an engine?
"Engine has the adapter plate and crank flange extension plate so a A727 small block trans bolts right up."
from time to time folks that follow slants are interested in the 727 adapter parts that you mention...
