4 brl Edelbrock intake manifold and carb

Intake model and carb number would help a lot here.

There are at least 6 different 4bbl SB intake and at least the same number of carbs.

If you aren't sure where to look, on the carb look at the front side of the left foot where the mounting studs go through.

Intake should have a clear name cast in it. If it's been removed, then look on the bottom, most of the time there is a model number cast there.
