1972 Pontiac (and possibly other GM) V8s. It is the same one as on my 455. It is a one-year part as the mounting posiition in 1972 switched from being perpendicular to the carb to parallel to it in 1972. Different V8s had different thermostatically calibrated coils and different vertical links, as well.
In 1973 they stopped using the choke stove system and went to a hot air tube, instead.
Do I win the prize for guessing the right answer? It is date code correct for my Canadian Firebird from Surrey, B.C.! [img]<<GRAEMLIN_URL>>/grin.gif[/img]
