Decoding a "68 z28 302" by the pad stamps?
« on: April 26, 2022, 10:06:13 PM »
Can anyone help me with these pad stampings? I included the block and head numbers although the heads are newer. It is "supposed" to be a Chevy 302 out of a 68 z-28. Is it? If not what the heck is it??

Three months from casting to build?

Heads aren't correct.  I don't see anywhere that shows the block casting date?  My comment was strictly about the pad stamp.

Yep and doesn't change my previous opinion on the stamp.

I see the same, which falls right in line with the Assembly date.

UPDATE: After further inspection, the engine is sized, has mismatched pistons, and a crank with the number 3941174, 327? So now my question is what is just the block worth? It is currently still 4” bore. The windage is intact also. Trying to decide whether I walk away or not. Does seem like the block should be with something though. 🤷‍♂️

It’s only going to be worth the most to the person with the car.  Oddly enough I have another Z 1,000 vins off this one in my data.  Just the block can go anywhere from $1k-3k depending condition.
