Ld340

Autopar

That cut in the diveider is to help balance the 2 sides at high RPM. I was also told that it was for the 3bbl. Holley or Carter. Which I'm not sold on. The 3bbl. carbs were NASCAR carbs and rare to find. You can see a picture of one in the Carter Carbs book. I think I can duplicate it myself and will try later come summer. Though it will not be a dead ringer, the main idea will be there.

The other LD340 that has the MP mods to it didn't have the cut in the divider.
