Well the balancer is easy to check out . Like I said there should be some type of cut or notch on the rear edge of the harmonic balancer , but I have seen 400's with a light scalloping on the front edge of the H-B or even a small weight tacked on the front side , after-market style . The 350 harmonic balancers are smooth edged . They also left a hair more material on the outside of the block at the cylinder bores on the 400 . you might be able to see or feel the irregularity . If it is in fact a 400 and you run in a hot climate , you should have a heavy duty radiator . . Good luck fishing .
