the biggest reason I can see not to use 3 carbs on these trucks is the rear one runs into the fire wall. At least that is the conclusion I came up with. I never actually bolted the intake on, because it seemed really obvious it wasn't going to clear, but then again that was 20 years ago, and I may not be remembering correctly. This is the same problem I am having with my fuel injection unit, the rear tube runs into the firewall.
