While they are at it - I picked up this 68 Monaco. it has the 383 v4 727 8 3/4 - but I don't know anything else about it. It was a project and we put it back together today. Anybody know what the rear end is? The engine has the two snorkel intake with 383 MAGNUM. It's a cool old car. If you knows how to decode this paper - I'd love to know. Sorry to jump on your thread - I don't know how to start one of my own.
