Gosh Hank,
are you always so quick to get defensive? If you would calmly go re-read Preacher No Choir's post, you will find that he was not bad-mouthing Webers, rather his distaste was directed at the 390cfm Holley. After he questioned the reasoning for wanting to use a 390 cfm carb on a 292 when most of us would not think twice about using a 600 cfm carb(or larger)on an equivalently sized Chevy, Ford, or AMC V-8, he then went on to explain why a Weber would work fine in this application. You took exception with the "O.K." semantics and in doing so, completely missed the point of the post.
I, for one, would like to know: when you use an L- designation in front of a number, when does it simply mean an inline configured engine and when does it refer to Datsun's code for a particular engine? Apparently Datsun has/had 26 different engines (according to your list) all whose designation is prefixed with an L. I think we can all agree, that in this isolated instance it is NOT as straight forward as you imply. As I see it, an L6 could indeed be Datsun's 27th engine with an L designation or it could mean an inline 6 cylinder(one of Datsun's 12 in this context). Just so you know.
