Hi, guys! New to the forum. Anyway, I was given a Buick engine my uncle built. All he told me was that it is a 350 Buick. Obviously, I figured out it was a V8 by looking at it! I wanted to find out more info, so I searched for the casting number, and I think I found it. 1382201 is what I came up with. I searched the net and found this out: Buick 350 V8 5.7L year 1968-71 Bore: 3.8000 Does this look right? I'd like to have some confirmation on my discovery before I start bragging to people on what I got! I'd appreciate it if someone could run that number for me, or give me another site where I can look it up again. I could not find another site to get the conformation myself, so I'm relying on you fine folks Thanks a lot! BTW -- I found the number towards the back of the motor, on the top, behind the carb. Thanks again!
