Is This A Series 1 Or Series 2 Rb30 Block?

[rigez]

Hi Everyone. First post on this forum and jumping into the RB world.

Like title says need help in verifying if this is a Series 1 or Series 2 block. Any and all comments welcome. I'm buying and want to start the planning for my engine build.

It sucks to view those photos on phone, but looks like you have the important part, the flat and tapped hole for the idler on the exhaust side.

cant see if the drain and oil feed is there but they are easy to add.

also looks like you have already ground the clearance for the exhaust manifold, plugged an oil feed to head and tapped the hole for the new tensioner. what are you worried about?

Its the later block, can see the flat tensioner section on the front.

Thanks guys deal went south. Looking for another block to work with.

I have a block you can have, it has oil feed/drain and hole tapped for idler bearing. Needs a rebuild as no 4# is scored, will cleanup though.

It's in Muswellbrook NSW 2333, if your interested.
