2020 small block race?

I spent some time talking to the BB guys on FBBO and couldnt get the info needed to do a chart. No offense but most would not even dream of running a BB car stock in order to set up the baseline. I also dont have the mopar BB background to set up that chart. I did think about picking up a Duster I know where is along with a stock 383, 400 and 440 to do that but too many projects.
