69 430 jet size???

[GS69350]

I'm in process of rebuilding a carb from a '69 riviera... The engine is original and mostly untouched and seems to run reasonably well.
The carb has been messed with, definitely rebuilt at one time, at least they put epoxy on the well plugs (though it didn't last!)...
Anyways, the jets on this thing say 54 - I wasn't aware they had a jet that small!!!! It doesn't seem right at all. The rods are 43b which makes sense. It seems to me it just flat out won't run with 54 jets if that is actually how big they are... The secondary rods are BZ , VERY small tips.

Basically just wondering what the stock jets/rods are supposed to be. (i would guess like 72-75)

Thanks

Factory set up for a 69 Riv was 70 jet, 45B rod

Thanks, that sounds more realistic....

Now to find me some jets and rods... where did I put them??

By any chance do you know the secondary size also?

Factory secondary rod is an AY.
By the way, all 69 big block carbs used this rod/jet combo
