What did you upgrade (Pics if you got 'em), and how much you looking to improve?

I did a major change on mine last week and put new heads on it, but no tracks here are open yet.......My goal is to put my Duster in the 5's this year! Would love to see +115mph......I have one more trick up my sleeve once we get this all sorted out.

And for the Cuda, I need street car like drivability for the cruise nights that are further away......I ordered a couple real expensive parts for that. Probably be here next week.
