Did they stamp vin on early blocks?

Thanks rusty im gonna assume its original and before i had the machine shop have it it was stock bore and crank was untouched. Not bad for a little over 200k miles.

It probably is. If the date codes are close, I would assume it is. Date codes are all you have to go by on those. That and see if the engine size matches up with the fender tag. If it does and the date codes are close, that's probably it.
