Correct intake for a 1969 340?

Is there a specific one (part #) more correct for a 1969 340? I have 2 intakes and one looks like a 1968 and the other a 1970.
Thanks!

68 & 69 show same casting # 2531915 70 is different casting # is3462848
depends how right you want to be

I have a 2531915. the resource I saw referred to it as 1968 and a 2531914 for 1968-1970?

The Mopar foundry, all of them, cast different parts with different casting numbers and casting dates for use through out the year
My point is that the lower casting number will be made before the higher casting number for the same motor in the same year, especially if they have a mid year update or design change
Look at your fender tag for the schedule production date and use the intake with the proper casting number that has a casting date before the SPD

one of my sources by l.shepard shows 2531914 as the service p/n and the casting # 2531915 68/69

There will be a date code on the intake too...

Thanks guys!

I have a original 340 intake I took off my 340 dart in the early 70's. I'll go out and see what numbers are on it.

Well the date code on mine 12 11 9 the casting number is 3462849 1

That would be a 1970 intake.
