OK, I think I know the answer to this question but want to run it by you guys. I've got a 1968 442 4 speed project car. It's been off the road since the early 1980s and everything I've checked has been the correct number except the carb. It's coming up as a Pontiac number, 1968 400 or 428 4 speed application. Since they're both 1968 big blocks and both manual transmissions is there any chance this could have been installed at the factory? I suspect it was swapped on in the early years as the crud buildup on it matches the rest of the engine. But before I sell it and look for an Oldsmobile application replacement I just wanted to make sure there wasn't a chance the factory ran out of Oldsmobile application carbs and stuck this one on there. Anybody heard of that happening? John

Too bad it wasn't a SD carb.

Ca-ching.

no, back in the days you're talking about, the carbs. weren't intechangeable. an olds 350 carb. was calibrated quite differently from any other gm brand. in the mid 70's-80's they did do that as they were sharing powertrains nearly corporation-wide(gm). example: an olds motor in a pontiac, buick, etc. application would have an olds numbered carb.

Maybe it was their 'first attempt' at seeing if it'd work across the board!
