Added info on the '64 Tripower intake manifold. Early '64 manifolds and those manufactured after sometime in February, 1964 have the same part number, 9775088, but the later manifolds have ribs on top of the water passage and on the entire bottom area. I believe these were added to increase the strength of the casting to avoid cracking.

Note that the big cars used the heater hose outlet as shown on the first picture. GTO's used a 45 degree fitting to tilt the heater hose outlet.

The first three pictures are of a '64 manifold cast date A284 (January 28, 1964). The second two pictures are of a later manifold, casting date G154 (July 15, 1964).
