If the motor is together, the only way, other than running the numbers, is to run your finger along the inside of the harmonic balancer. You will feel a balance weight. The 400 is externally balanced. That is why you always have to use the flywheel from the 400, as well. If the motor is apart, it is easy. 4 and an 1/8th inch bore, verses 4 inch, on a 350. Siamese cylinders on the 400, which only has steam pockets, rather than water jackets. The larger bore would not allow water to be used to cool the cylinders.
