New here with my first Mopar

Thanks guys! Yes, she moves well with the 340. What I know from talking to the guy who built it and owned it for 36 years is it has 355 gears in a sure grip rear end, 727 tf, the eng is a 71 that was rebuilt about 10,000 miles ago .030 over with a purple cam.

It runs like a top, but I know I can get more out of it...but before I do anything I just want to pay it off and enjoy it. I can't wait to get ideas from you guys. One thing that is bothering me that I want to fix right away is the drivers side vent window; if you open it there is no resistance and the wind blowing past it closes it back up. I haven't had a chance to dig into it yet but hopefully it's a quick and easy fix.
