We saw a ua on the crank , the new owner says he sees a 2 in front of the ua.
some other numbers we saw 2e31 on the
oil filter housing,
352a on the back of motor. 53 back of motor, 252618 back of motor, c6ae on the connecting rod bearing caps.
did ford use 390/428 parts together in 428 crate motors in the 70's ? The motor was bought as a 428 FROM FORD !!! any help
would be great . Thanks
