are there 3 iron 440+6 intakes 2946275, 2946276, & 2948276?

is this 2946275 or 2946276?



My cars engine assembly date is 9-11-69, what would be an appropriate casting date for that assembly date? Apparently, either casting number would be correct, either 275 or 276, yes??

I was thinking a range with in 2 months prior casting date to engine assembly date would be correct, what do the experts here think???

Many thanks!!!!
