A V8 into a 63 valiant

I don't know what else to tell you. It fits. It will work. I cannot lead you by the hand and throw it in there for you. People have been putting big blocks in the early A since they have been made. You can make the mounts like pishta said or you can get the Schumacher mounts. If all that ain't good enough for you, then I am sorry. I don't know what else you're lookin for. A picture to prove it? I am not gonna sit here and tell you something that's impossible to do. It's 2015. Everything has been put in these litte cars by now. Even Hemis. The low deck motors need such little mods to fit, that it's almost fair to call them a bolt in. You will never find out though doing research on the internet and looking for the end all be all answer to your question. I told you it is on BigBlockDart.com. I found it when I was lookin for answers for my 63. It took some digging, I admit. And you're right. I've said it before myself. When you start askin people for exhaust pics for big block early A cars, everybody clams up. I don't know why. But it's been done, it's pretty easy to do and it's damn near a bolt in with all the right parts. That's all I can tell you and if it ain't good enough then oh well.
