N1 Rb30 Block?

[Gts4RB30]

This maybe coincidence but i found this today on my new rb30 build. I have several other rb30 blocks with v7 on them. Any ideas?

Someone probably stamped them on?

Maybe, but my mate at nissan said they do it from factory and said hell look into it because hes never seen n1 stamped on a block either without it being the genuine thing. We also weight this thing at thr machine shop and it came in 8.4kg heavier then the other rb30 blocks i have???

I agree someone possibly stamped it on there.?

Manufacturers often use the "same code" to mean completely different things on different engines. Given that the RB30 and the RB26 are in fact completely different engines (from Nissan's point of view) I wouldn't be surprised to find that it means nothing in particular* at all.

* Nothing interesting, anyway.

Probably just a production run designation. Could be for diesel or South Africa cars?

Ok cool. Bit weird still that the block weights between 8.1 to 8.6 kg heavier then 11 we have?
