I have a Gen 2 hemi with the 2 four barrel set up and I measured the pull and it was 25 lbs. to open the carbs that are synced together. I complained to FItech and they say they don't have a problem. I can not feather the throttle with that much pull. There's not much you can do with the linkage because you have to use the Mopar adapter for the linkage. Everything is designed for chevys.
