Default Re: SO who came up with the GMC V6's???

GMCNUT, for the most you are correct except for a few things. GMC was not married to Pontiac in the 40's & 50's nor did Pontiac engineers design the GMC V6. In the 50's since GMC didn't have their own V8 they chose the Pontiac V8 and of course the was an excellent choice since Pontiac had larger displacement engines, but the Pontiac V8 wasn't the only V8 GMC offered. Trucks that were larger than medium duty used Oldsmobile V8's because of their low end torque. With the introduction of the V6 that was GMC's remedy to be self sufficient by having their own powerplant, As bigger V8's came around the 305 definitely didn't cut it so the 351 was brought out in the light duty line in 1966, an improvement but demand was there for high horsepower V8's so in 67 they brought out the entire line of Chevrolet engines. That was GMC's downfall as it got much easier to produce trucks that were fully interchangeable with Chevrolet, too bad GMC didn't stick with the Pontiac V8's, It wasn't until around the mid 90's that GMC and Pontiac combined to be the same division and that lasted till 2010 when GM killed off Pontiac.
