I kinda think mine is on of them. Got it as close to what I thought 26 degrees would be when I installed my bhj but I do feel like it's not exactI’m really shocked that BHJ did not mark this location. It’s possible I have an early style but after days of looking I have not found a single dampener that has a mark at 26’ ATDC. Even BHJ site the picture does not show it. The long mark is 0’ and that’s all it has. I’m sure there are a lot of 3.8s out there with fuel injection timing way off.
