Yes, it is a shame to see them go down.
It was a Pontiac (1973 SD Trans Am) that brought me around to understanding big block torque. This was doing my "street racing" days in 1975.
I was stationed at Andrews AFB in Maryland and we use to race from the DC line down into Maryland. I was very, very competitive with my solid lifter, 457 geared Mach I until one Friday night when I got "suckered" into a rolling start with this guy in his Trans AM. To make a long story short, he "handed me my head" on a platter - - three times straight. That, as I said was my introduction to big block torque and the different RPM ranges where it occurred. The '73 SD were actually "better" than the earlier "Goats", based on my experience.
It is really too bad that the decision was made to discontinue them but who knows they may come back - - strangerthings have happened!
