Actually in 67 it would have been an SM420 transmission. But the 250 is kind of the odd duck in a GMC, Usually they liked to run a 292 or there 305 V6.
My 67 was originaly a 250 truck then I yanked that in favor of a 292, then in went a 350, after that was a fresh 292 but I burned down #5 I discovered a crack in the intake manifold, After that was a cheap 230, then this last spring I tossed in another 292.
I prefer my cylinders be in a row and to shift my gear manualy.
