Introduced for 1973 and lasting only two model years would be the
Super Duty 455 available on the Legendary Trans Am. In 1973 only
252 units would be produced including 180 automatics and 72 4 speed
cars. Very under rated at 290hp, the SDs were producing performance
numbers that everyone was more accustomed to seeing in 1969 and
1970. The SD-455 has been accurately described as Pontiac's last
stand and the last real muscle car. The SD-455 was a thinly
disguised race engine: four-bolt mains, reinforced block, forged
pistons, forged connecting rods, nitrided crankshaft, even a
provision in the block for a dry sump oiling system. The SD-455's
cylinder heads were a free-breathing design patterned after the
howling Ram Air IV heads, and the cam was similar to the grind used
in the Ram Air IV. In 1973, the SD 455 ran the quarter mile in
13.751 seconds and at a terminal speed of 103.56 mph. That was
fast. That is outrageously fast and it was done in a street legal
car a 1973 street legal car with a full tank of gas (3854 lb. curb
