No TJ you are not dumb...remember
In the movie WarGames, where s super computer called the WOPR takes over the NORAD missile defense system and almost starts a nuclear Holocaust, Ferris Bueller (young computer savvy kid) saves the day by teaching the WOPR, the strategy of the game Tic Tac Toe. The futility and eventual end result is that the WOPR realizes, with its new found knowledge, that nobody wins, and ultimately cancels the nuclear launch.
So it is that we begin to understand the futility sometimes in trying to explain to parts stores that GMC did in fact make a 305 V6 and that "No, it's not a Chevy v8."
And we continue, on our own, and with the few others who have come before us, to create a better strategy. A GMC win strategy in procuring parts, finding other alternatives and others like us, boldly going where no small block has gone before, thusly keeping the GMC V6 ALIVE!
...You are one of the chosen few TJ
