Opinions please! My stock 289 2v has ported vac advance. I've heard manifold vacuum can improve mileage. True or not? I'm also trying to get it to run better on this lite beer that passes for gas in Arizona these days. I've backed the vac advance diaphragm off to almost nothing and still get a little ping on acceleration. I'm thinking the manifold connection would help that.
