George's pics show exactly what was there. The 67 big block cars came with a factory 2 * 4 induction system with a black "cobra" air cleaner. The carbs were 600 cfm holleys (made for the 2 * 4 application) and were mounted backwards. As Georges pics show, the engine also had crappy exhaust manifolds very similar/or same to the 67 390 GT Mustangs. Kind of an exhaust tournequet - in fact the exhaust system was probably responsibile for the so so performance numbers in the rags at the time. The first thing we did back then was can the manifolds and put on headers. In 1972 my stock 500 could turn a high 13 @ 105, but that was with the transverse muffler excised (with stock manifolds). Later, it was popular to try to add the 428 CJ exhaust manifolds, as they were better. There was a subtle difference between the 67 & 68 valve covers. I am sure that SAAC has the specifics, but I am not aware of any "normal" 67 500 having a single four out of the factory.

Still have the car today, engine is exactly as George's pics indicate.
