Hello. March 29th '66 is the date the block was cast. There should also be an 8 digit number cast on the passenger side of the block beginning with a 2 or 3. There's usually a "GM" there too.
May I ask how you figured that out? I really want to understand all this stuff, but I know you guys with experience have a secret stash of knowledge.
Now this casting your talking about is that by the firewall? I see something there, but its super hard to read and I think I
would literally have to pull my hood off to get down to it. I'll do it, but I just want to make sure thats the number your speaking of. The one I did find is something like this. C0N2 0296 or maybe its C0N2 C296, but I didn't see a GM stamp near it unless its under the crusty build up.
All the numbers I did find I posted up above in my first post of this thread. I'm super eager to look and relook just so I know what I have.
I did notice by the distributor there wasn't a vin number stamped on that pad near the F0330BN number.
