If anyone read my post before, I thought I spun a bearing on the motor. Well, the car got towed to my house and my father started to work on it (not usually a good thing). Well, he did some digging and found out the flywheel was cracked, and that caused the noise. The car runs fine. The flywheel had about 6 cracks down it, and there is now a new flywheel there. When he called me and told me what was wrong with it, i told him dont even tell me the tranny is blown. Hes like, your cose, then tells me its the flywheel. My first response: "BUt I really wanted to build a 383." Oh well, theres still time later on.
