Anybody have pics to post of an ld340 intake modified to fit a thermoquad carb. I know there is a diagram in an old Direct Connection catalog
but it is not clear to modifications needed. Thanks

I bought mine like this. Looks like it was trimmed to match the gasket.

I just did this one for a guy.

Someone JB welded the center divider back in.

This job makes a pretty good pile of chips.

I would consider the Weiand 8007 action dual plane, it already has the spread bore flange but it does require opening up runner exits (the roof is necked down to 318 size)

I already purchased an ld340 in very good condition for $50.00. I have seen the direct connection diagrams which basically match the
two photos but they have the divider milled down.
Any input on this modification?? Thanks
