I would like to move the whole accessory drive serpentine belt closer to the block on a 5.3 by using either a LS1 or Vette dampener (to gain some clearance for a swap). This would of course require relocation of the accessories and a different water pump pulley. Would the LS1 AC and alternator mounts work on the 5.3? The LS1 tensioner? I'll be deleting the power steering pump and placing the alternator there.

it will fit on the crank if thats what your asking but it won't line up with accsessories of course but it will go on i accedently put one on mine when i did my swap lol. but when i went to belt it up i figured it out and swap it back out.

 

Those dampeners are pretty nice and I would love to put one on myself. I think if you pay ASP enough, they will make you one for a truck. At least that is what I heard from my engine builder. The price quoted was around $750 though. A little much for my taste. The truck crank pulley does have a rubber dampening ring around the outside of the mounting hole.
