I have two SBC blocks and cannot find their year or displacement from the casting numbers, which are: 14023436 (I think, could be 433 instead). Second casting number is: 14023633. Any help is greatly appreciated.
What is this engine?

It looks like you have a couple late model 1 piece rear (1prms) main seal blocks , you can kinda narrow it down a bit as to weather they are late 90's or early 00's blocks or if they are marine by seeing if they were cast and machined for mechanical fuel pumps , early 1prms blocks were not machined for roller cams , 350's had a slightly larger balancer than the 305
