Hey Mudnut...
no need to yell!! (cap lock...)
You are right about the 4bbl on the Stroppe Broncos.
That is (to the best of my knowledge) the only EB to come with one.
But they were not a factory prepped vehicle.
If you are looking for recommendations on what to use... it depends on what you are building and what you will be using it for.
Low, medium and high rise, single or dual plane. Cast iron, aluminum.
Anything that can be used on a 289 or 302 is available ...
