Hi bowcofin
That number is on the passenger side of the block at the front, just aft of the water pump. It’s a small flat area that sticks from the block that the water pump is attached to. You might also find a VIN number for the vehicle that the engine was installed in, the VIN number is not always there. If someone painted the engine that number could be covered with paint and hard to see, also if the engine has been rebuilt and the block deck has been machined the numbers could be removed by the machining process.
All the small block Chevy engines look very similar in appearance from the outside and many parts between the different engine sizes can be interchanged. For example just because the valve covers say it’s a 350 doesn’t mean that someone didn’t put some 350 valve covers on a 327. So a good starting point is the block numbers before you start rebuilding or trying to find out what you have.
Finding out what the numbers mean is a lot simpler now days with the web. Just do a web search for ( Chevy block numbers ) and you will find a number of web sites that list the numbers and some will even tell you where to find them and what they mean.
Enjoy your build
