That's the engine that had the Short and Long Ram intakes

for the dual four barrel version from the factory. The "short" ram intake had the carbs pushed out over the valve covers, one on each side. The Long Ram intake had the carbs over by the hood hinges on each side of the engine bay. Those Long Ram intakes were still cast iron and weighed as much as the block.
