Pulley Alignment is the Bane of my Existence....

Not much help from me, but mixing LA pump/brackets/pullies etc with a Magnum block can be a pain in the arse! Looks closer in the last pics. I dont like the looks of that plate( or whatever it is( behind the bracket. Check Bouchillion performance they may have what you need? This is why I like stock matching stuff.
Good luck!

Thanks! It's actually still a LA block and head combo, last year for those. But yeah making sure every single bracket and component that matches and lines up has been a major headache. I just want to drive the dang car!

I'll look into them, but that plate behind the bracket is the triangular bracket that goes behind there and bolts to the water pump (I guess for more support?) . I just placed it back there for spacing reference to make sure the pulleys line up properly.
