Whats up guys, First post. I've got a question hopefully one of you guys can answer. I've got a 383 and its really rusty/grimy but tonight I got most of the numbers visible and I was seeing if I could get a crash course on what numbers mean what things. I obtained 3 sets one on the left side of the block another on the left but near the freeze plugs. and another that was mirrored on the right side.

Thanks

 

If you need help, then you need to post the numbers so someone can help you identify what you have.
