On the Block Vin Pad are you talking about the Machining Marks that look like it was cut From left to right? and with it being a 7-25-69 block does it make it correct as a warranty block.
It might be hard to see the actual casting date, but could it be a 9 instead of a 7?
If you have some time, take a close look at the block, just above the flat, machined pad. Sometimes, there are numbers stamped into the block. Just above the raised pad where they normally are stamped. If it is an actual warranty block, there probably will not be any numbers there. Here is a picture of a service block Blue metal tag.
