318 combo's

Guys,
I really have not read through all the pages of this thread, BUT, I have a question that was asked to me over the phone, and I simply could not answer it, truthfully.

Building a 318.....was there EVER a 318 dual carb intake? like a 2x4 set up? I know this is a novice question, but my Step-Son asked me if I knew of anything like that, and sadly, I don't (I'm not familiar with what was offered for a LA 318, as far as after-market parts are concerned, I seriously doubt anything like that was EVER made by Ma Mopar..... Which, I relayed to him. As one of his friends, had a Dart (I'm unsure of the year of the car or the fact that I have ever seen this car) I'm not sure of what has been done to the car, if anything, but he's looking to do a little, Nothing serious as far as boring, and or stroking goes but.....bolt on simple things (HELL, I'm not sure if it has headers at this point or manifolds) BUT, see, I'm trying to see if I can give him ideas to help his friend out a bit. I may possibly see his friend today (Sunday) so.....doubtful I'll have any info by then! BUT a phone call is all that would take!

EDIT:
Did a bit of research and come up with Offenhauser to make a dual quad intake for a 318.. problem being, I'm not sure if they are talking about the 318 A Poly motor, OR a LA 318... The price is a bit steep but, then again, it is a rare part I suppose. Anyone know for sure? I know a dual quad intake was made for the 318 Poly, but I'm not sure of a LA 318.....
