The number one cylinder is at tdc the distributor rotor is pointing to number one but the marks on dampener are way off like a half turn or 180deg. Im thinking the dampener slipped and a mummert dampener is in order? Is it a tough job? what does it consist of? Any special tools? Any answers are highly appreciated 25 years old and I love my 57 fairlane that I inherited the y block is awesome.
