Nothin. Atleast nothing that u need to know that is specific to the block. You're looking for C,D,E,F on the side of the block where the starter is. C-60's,D-70's,E-80's,F-90's....the 2nd number tells u what year. Like my block that i just got is a D4 for 74. The one before was a D8 for 78. There are a bunch of numbers after that but i dont know what they all correspond to.


Good luck finding a good block. I just spent the last 2-3 weeks searching for a decent 69-74 locally. I went through 3 blocks before finding a good one. Now the fun begins

The WCP9 is for windsor casting plant, core set 9, like other said, the numbers on the underside above the starter are specifics you want. Being from windsor, all these great motors came from my hometown, and my whole family works there so getting info is pretty easy.

What was the last year for the high nickel content blocks? I believe the number on mine says D8, so that would make it a 78?

Getting info is easy, but what about getting 351 blocks for your canadian friends

I can see a wonderful friendship resulting from this thread
