I can't seem to figure out how to send photos in a PM here, so, I'll post them here along with their descriptions in case others want one. I have 4 LD340 intakes. They're all for sale, but, bnichols has 1st choice, and blewbyu has 2nd. Ok, manifold #1 looks unmodified, has the Chrysler part number, but, has one damaged carb mounting hole. If you have a carb that can use the inner hole, no problem. If you need the outer holes, you'll have to fix this one hole. I don't see any other problems.
Manifold #2 doesn't have the Chrysler part number, and looks like the thermostat area was repaired. Looks like a good repair and I don't see any problems with it or anywhere else on the manifold.
Manifold #3 has the Chrysler part number and has had part of the inner divider removed. I understand that in some applications, that is a desirable modification. I don't see anything else that has been changed or that is a problem.
Manifold #4 also has the Chrysler Part number and I don't see anything modified or wrong with it.
Before I ship any of them, I'll go over them again in more detail and inspect for any problems. These are all just as I pulled them from engines years ago. Pm me if you are interested in any of them and I'll put you on the list in the order you contact me. Thanks, Mark
