Are my 440 engines a rb block?

[HersheysHemi]

Hi
Two 440 engines came with my car and I want to start ordering parts to assemble the 1968 block since it looks to be the better of the two.
Can someone please confirm these are rb engines?
Im new to owning a mopar.
Casting numbers are
25384306 for the 1968
3698830 for the 1972
Thanks

Yes, 440's are RB (Raised Block) blocks

You might have to ask the block what it wants to identify as.

Ok I thought so based on research I did but wanted to confirm before spending money and ordering parts.
Thank you

.... unless, of course, it's a radical stroker small block.......

(.060 over 360 block with a 4.25 crank is 440.17 cu in. Lol)

The casting numbers tell me big wedge.

That 68 should be 2536430? I don't see a 2538430, maybe my list is not complete.
