340 block value?

It must hold up I suppose.
I was a little concerned at first, as the gear now runs against the aluminum pump cover, instead of the iron cover.

I've got an engine that only ever had an aluminum cover with a twin gear pump design (and an AL housing). Not any issues besides normal pump wear (from crap out of the pan), and the downward thrust on the shaft is taken by the bushing, like YR sez.
