FFR I appreciate your help! I got the old bugger pulled today. So it's celebration time I lost my virginity.lol. The only problem was when i pulled it I broke a piece on the bell housing, maybe where a stud goes in at? That's what it looks like. Anyways. After I got it out and cleaned up a tad more, I found only 1 more nunmner on the back end driver side. : 8J175838. I've got the Steve Christ book on rebuilding Big Blocks. I read in there, that 428's have dishtop pistons w/ 4 eyebrows. Mine are like that. They look the the picture int the book that says the compression should be 9.5:1. regardless I need to find out what I have before I decide on what to do as far as replace/rebuild etc.. If I have something worthwhile that I can get some performance out of Then I'll get this one all cleaned up and stuff. If it is just a standard model that will cost as much to rebuild as it would to pick up a crate motor with higher performance than I'll go with the crate mortor. I want to get at least 400 HP put of it. I saw that a builder called "Tuffdawgs"
offers that kind of 390 for about $3700. can you tell anything from that number I found? - 8J175838- This was at the rear driver's side of the block.
I don't have any plans for the drag strip but I would like to be able to hold my own when I pull up to a "rice burner". Once again FFR thanks for everything.
