Not all. I know for a fact Chevy put 305’s in their trucks in 1982 that did not use the same manifolds, the bolts around the #8 cylinder are farther apart than the standard 350 bolt pattern. Hence the existence of this bracket.

I don’t know if they put those 305’s in early thirdgens but I know they did trucks (and also el caminos I believe).
