A good Friend of mine asked me if I would check his LD 340 on my flow bench today and I myself was a little curious so I mounted a small block edelbrock to the bench and did a flow test on the head. We then bolted his some what grubby looking intake to the head. This was a used intake that was never touched with a grinder so it was not even gasket matched. Here are the flow numbers.

head head with intake
100 60 62
200 137 130
300 200 187

400 251 224
450 256 239
500 267 247
550 273 249
600 275 254
650 276 255
700 276 255

I always knew that these were good intakes and after doing this test it backs up what we have seen at the track for years. He wants to see the results from Matt's Victor 340 intake and if they are close we will do some gasket matching and touch up work to the LD340. Here are a couple of pictures of his intake so you can see how much better it could be with some work.
