These are the best pictures that I could find. I know that I took some others that showed lots more of the yellow after I stripped off more of the orange paint with a turbo nozzle on my pressure washer, but I can't find them. I'll post if I can find them.
The reason you won't see any yellow on the block itself is because the engine came out of a '57 cement mixer with a replacement '64 block. Everything on the engine except the block had the yellow paint.
