GM part # 7029922 is a rather weak spring that was OEM for HO Pontiac engines from the early ‘70’s. It delays enrichment until vacuum drops to 3 in/Hg. This spring will work with durations >/= 230 degrees @ 0.050”. Another GM p/n is 7037305 for a PP spring that is set for 6 in/Hg, and would work well w/a high vacuum, smooth idling and/or wide LSA-type cam. Thing is, unless the parts counter guy is cool w/you, they come in packs of 10 springs. | GM part # 7029922 is a rather weak spring that was OEM for HO Pontiac engines from the early ‘70’s.
