I'm hoping a new belt and proper tension will fix the alternator belt. I don't know what would cause it to be misaligned. I dug out the other set of pulleys and they're identical. My recollection was incorrect - the crate engine WP pulley only had one groove that appears as if it lined up with the alternator. The stock engine WP pulley has 2 grooves - one for the alt and one for the ps pump. That's the one that's installed. Both crank pulleys are identical, with 3 grooves. The third groove appears to be for a second ps pump pulley which I understand they stopped using at some point. I've seen older (70s) 454s with both belts, but it's obvious a belt has never ridden in that spot on my ps pump nor on the crank pulley.
