What can you chevelle gurus find wrong with this?

[BBIGG BLOCK 396]

And the trucks with the 402 also had a emblem on the front fenders that said 400 not 402.Although in reality it was a 402 C.I. Big Block and not 400 C.I. was this having to do with Getting insurance on the cars back then or something.I know I have heard stories to that effect but nothing ever in writing from GM.I know that is why they cut the HP ratings back on the models that are being talked about was due to insurance at least I remember reading that in some form before.
