i just bought a 289, the people didnt know what it came out of and im having a hard time figuring it out. the intake is stamped 289 4 C50E-9425B i also found a stamp that says 7D5Z i believe its the date? any help would be greatly appreciated

The 7D5Z means the engine was assembled April 5, 1967.

and the

Are you sure that's C5OE and not C6OE? I found a listing for an intake manifold with C6OE but not C5OE. Basically it's a 4 barrel intake manifold for a Mustang/Falcon.

intake manifold is definitely C50E, but the exhaust manifolds are C60E-9430-F and C60E-9431-F

weird cause intake is 65 and exhaust manifolds are 66
