Hello! I just got my 64 Cadillac series 62 2 door hardtop, I traded my 74 coupe deville for it. What I was wondering is what temp thermostat should I run? The engine has been fully rebuilt, has never been started. What else should I do? Prime the oil system? I am a mecanic but I have only had 1 rebuilt motor and that is my simple 327 small chevy! How are your expieriences with the 64 429? I had a 65 coupe deville years ago with a 429 but I know its not the Same as the 64 motor. Sorry for so many questions!
