Throttle Pressure Link Problem
on a 2 bbl to 4 bbl swap to be done right needs many parts changed. heres a hint the pull pin on a 4 bbl is more forward and to the left than a 2 bbl. some times even the pull cable is longer. just do better research. be sure and get it right, else you have a WOT jam. the slot at idle should be full forward. the reason is if snow jams the linkage at the bottom so you can still close the throttle. it happened to me on 1954 chrysler new yorker 331 Hemi.
