What's missing? 727 BB

Got the numbers off my trans. It's early 70's 383 727. Maybe I should look for the parts and build this one?

Barracuda Early 70 8-383 2bc
Challenger Early 70 8-383 2bc
Chrysler Early 70 8-383 2bc
Dodge Early 70 8-383 2bc
Plymouth Early 70 8-383 2bc

Here is what I found on another site. It seems like 1970 was a split year for a big block 727 based off your early and the date below that confirms it.
