not sure if my 88 b2600 4x4 had one to begin with or not, but probably not. last owner was a junkyard dog/weekend racer, and the hood on it is a charcoal color (truck is black). he never mentioned anything about a bubble hood, but the supports in my current hood are 'trimmed' to fit the air cleaner on the chevy 2.8 engine in it.
i suspect the bubble hood was designed so for the height of the fuel injected 2.6 intake manifold... carb trucks probably wouldn't have had them. could have been just a whatever deal when they had the bubble hoods made... throw it on whatever carbed or FI'd 2.6.
