Any pictures of it so we can see what you are talking about? If it needs a ton of work might be better to get an Eddy air gap. But they are both great intakes, I think they are rated as the best 2 manifolds you can buy for all around performance. I have an air gap on my 69 340, stick X heads, MP purple .509 can and a 750 VS Holley and it works great. I also have a nice LD340 that’s for the old Direct Connection mid for a thermoquad, haven’t tried it yet. If you go air gap….don’t cheap out and get a knock off China version, get the one from Edelbrock. Another thing to consider, if “down under” shipping might be a lot for you…could use that $ to fix your old manifold.
