Figured I would post up to see if someone can figure out an issue I am having with my 350 block. The engine stamp is 3970010 which doesn't really say much, but I am trying to figure out what is up with the suffix on the passenger side front block near the water pump it says V0302CLY. Now deciphering this and you get the (V) Flint (03) March (02) and here is where I am lost. According to this website http://www.nastyz28.com/gm-chevy-cod...s-suffix-2.php there is no such thing as a CLY code. I can testify with 4 other people that the block does in fact have CLY at the end. Can anyone figure out what it is?

 

What difference do you think it would make?

Maybe there's some way of actually coming up with useful, useable, actionable information? Which suffix codes ARE NOT once the engine had been disassembled.

You know it's a 010 block. That tells you everything you need. The other is just an exercise in mental waste.

 

It makes no real difference other than knowing what the engine came out of.

Exactly true. It is a mental waste to be honest, but I was just curious.
