i installed them via the 4 bolts on the bottom
What dual intake manifold? dual Edebrock intake? can you post a link a photo of the intake?
How many holes per carb on that manifold (4)?
Did you need adapters (carbs to manifold)? As I recall, the C-W carbs have 4 bolts and most 235 dual-carb intakes have 2 bolts per carb.
Can you post a link to photos?
