Don't worry about sounding mean, all I'm talking about is from memory. I thought they were called inline 4 barrels, and there were two of them used. I have an old Autolite manual around somewhere that may have them in it. Maybe they considered it to be a fuel injection, as technically carburetors inject fuel, just not in the sense that TBI, TPI, SPFI, and all the other high pressure means of fuel injection do it. If you look closely, it appears as though there are float chambers around each barrel. Again, let me see if I can find the info on this.
