I recently picked up an intake manifold that had a raised buss on it, That I thought was for mounting a horn. Now that I have it in hand there are no mounting holes for the horn. Did the 235 intakes come in a version that had no holes and need drilled, or with cast holes for the horn, or am I just plain lost, or do I need to keep looking for the right intake manifold? The 52 has rams horn hi and low horns, but I like the look of the single horn shaped horn. Any sugestions would be appreciated.Jimmie.
