Engine Stamp look good?

[67 L78]

While I own 3 67 L 78's 2 are Baltimore cars and 1 is a Kansas car. Comparing my stamping to yours they look very close. My concern is why the broaching isn't under the stamped numbers? I see it back close to the head but it looks smooth under the stamping. I have found more cars that weren't real than one's that are. If I were buying this car I would be all over every thing checking dates. Does it have the big radiator?? That will cost you 5 grand if you find one the carb. the distributor these are very important L 78 only parts. Does it have any paper work very important to check all these things before you lay out the cash.

Not a real good picture of my Kansas stamp but maybe it will help.
