Yes dizzies are supposed to be ported but I do need to replace mine and putting it on manifold advances it sooner. My carb is a fresh rebuild edelbrock that I haven't really messed with alot, I bought it and installed it and then I got my blazer and really haven't drove the BB. The truck dieseled badly with the quadrajet on it. I do plan on rebuilding the q-jet when I do the head gaskets and put a new intake on, I found a dual plane spread/square bore for $250 so I can run either or, I just need to find an electric choke for the q-jet and I will be good to go.
