I see what you mean. I am going to test fit the
oil pan tonight and see what I need to do. I went over to a local engine rebuilder and got a correct size key for the crankshaft. Man, this has been a serious learning experience. And, this is a very informative post. It is amazing how wide the spectrum of different FE builds. Looks like I came in at a good time to build one with the aftermarket parts available now. Seems that some years ago much now was not available then. Thanks to everyone for the replies to my post
