Based on what I've figured out so far it is a factory 4 speed car with M20 and rear antenna. Original engine and tranny is not in the car but does anything about the above number tell if it is a 250 horse or 300 horse 327? Car has a factory tach in it.
What are the numbers on the pad,front right just below head on the block? If you have an AFB carb. and camel hump heads,2 1/2 exhaust manifolds you have a 300 horse engine if it is orginial to the car.
