Issues with 340 distributor

Ahhh thanks a bunch you guys. So you think the hei setup is worth going too? I mean the car runs strong, 400horse 340. Just always seemed like it wasnt quite 100%. Possible my advance wasn't set up properly? Just weighing my options, not a race car but a street car. I would hate to remove the wiring i already have. Unless that kit is super easy to install
