Hey there, im in southern MD too. Your welcome to come by and check my cars out. If you need help with anything you can pick my brain. I have been a mopar fanatic for nearly 30 years and have owned many A bodies. I currently have a 73 340 dart sport, 73 swinger (cloning to a 72 340) and 74 cuda (cloning to 71 340 six pack, shaker).
I have a 340 with EFI on the test stand you can check out. I went with the MSD Atomic EFI and so far I love it. I saw your car a while back in Bills paint booth and was checking it out. I can say I dont recall seeing a car with that mist green paint before.
