Got Shell 93 Octane and now barely idles 1973 Dart 340

That is good new to hear that I made a good decision. I put at deposit down and spoke with Mike about my current 1973 340 with a 727 transmission. He did say it comes with the 360 damper and flexplate. I need to give him a call to confirm the electric choke on the carb and will confirm that I need the 360 to be balance correctly to match the transmission. I did not know for sure what the current year engine/trans is in the car, just what I was told at the sale.

So if it comes with the 360 LA damper and flexplate, then do I still need something for my 727 torque converter? Sorry, I am relearning the Mopar specifics from my high school years (mid 1980s).
