In MY '67 you could order a C/10 with a 230, even. Or a 292. And I guess a C/1500 with a V6 at the GMC dealers.
A Marine buddy used to have a '68 GMC C/3500 [one ton] Flatbed with the big V6. 351?

I became a GMC owner in 1995 when I bought a '71 GMC Jimmy ''Custom'' K/1500. [Not a K/750] Both Blazers and Jimmys were all built on the St Louis line, 1970 and '71. Flint Mich joined in on the Blazers in MY 1972. [And Jimmys, too -- I guess.]

Funny how some people will defend their ignorance.
