New Mopar owner and eager to learn!

Hi there folks... just a quick introduction to start on whats sure to be a long informative road.

I just picked up a 1971 Duster, 225 engine code which also came with a 1974 Dart Sport 318 parts car. Both cars are in reasonably sound shape, minor rust on the quarter panel bottoms. No engines are in them but previous owner was going for a big block 440 Duster so that was included. Block casting is 4006630 440 9, tag on top is 6T440 E HP. Heads are 3462346. Im already eager and feeling a little lost hahaa. I think sharing the build and listening to good advice will help this be easier. I included a few pictures from the day I got them. Take care and thanks in advance for the help thats sure to follow from here!
