That is the correct block also and has a 303 date code so that also fits the car. This is a really special car to be documented that well and so original. One interesting observation, It does not have the external depressurization valve so not sure if the recall was ever done on it but at the same time, The screw is missing in the carburetor float cover that holds it on. The radiator has been re-cored also. Boy, I sure like this car. I hope it goes to a good home.
