Vapor Lock Opinions

With my old engine 360, edelbrock torquer manifold and edelbrock 625 carb, it would vapor lock all the time, truly was frustrating, the new motor I have edelbrock clone airgap, 1" edelbrock phenolic spacer and edelbrock carb, still only using mechanical fuel pump, and it has not ever vapor locked in 2 summers, and we've had hot summers too, many times over 90 never had an issue, so IMO you only need the spacer and trailbeast is correct get the Phenolic, although it might be that I went from a single plane manifold to a dual plane too, not sure..
