Bolt spacers

Hey mike, any thoughts on why the photo you posted has a alt bracket with a bend in it and a longer spacer between the head and the alt? Is it a 273 - 318 vs 340 - 360 thing. I see the water pump is different and maybe the timing cover is deeper???? Pardon my ignorance on this.
I don't know. It's just a photo I found on the net that showed the bushing in the ear.
