sorry! I have no idea what series and as far as pictures,the only way I can get them to you is email, for some reason I can't seem to load pictures, it tells me that it's loading but they won't come out, the few times that it did they were too big,I miss spoke when I said about the blue paint,I took a closer look and it's been sprayed,I noticed the valve covers have ten small bolds,there is some numbers on the intake manifold which may or maynot help also between the block and the water pump,I know it's not much help, but I've never worked on an Olds so I'm really lost here..
