all I have to do there is swap the aluminum coil pack bracket with the cast iron one (99 + only) and run the custom standoff with washer and idler pulley with the matched accessory belt to the ss pulley. and I dont really want to tear into all the pulleys until I need to, and then when I do I will allready have the MPS. also later on when I do swap to L67 pulleys I will be doing a cam swap aswell. right now I'm trying to get as much porting as I can done to everything before I do the install. I am going to paint It all too
