I have some money burning a hole in my pocket and decided to get an underdrive pulley setup for my 6.2. What all parts do I need to get together for the installation??? I have found some information about this in the past, but my search did not accomplish much this morning.

This is what I remember:

UDP
new crank bolt
balancer (UDP) install tool (needed???)
new stretch belts
belt stretch tool???
overdrive crank pulley (optional)

Any help with part numbers and or cheapest place to buy this stuff is appreciated. I know that the gains with the UDP are not great for the money, but I am still trying to decide which headers to get...wish the calspeed 1 7/8s fit the NNBS 4x4s.

Thanks in advance,

 

Check marylandspeed. Believe they offer package.

I've been thinking about the Cal-Speed headers not fitting 4wd's, stainless is prone to warpi g when hot right? What about mounting the headers up and letting the truck so the headers get really hot then manipulating the tubes with a crowbar so they fit?? I wonder if it's a plausable solution??

 

I suggest anyone pulling the pulley off of a NNBS gets a 99-07 AC tensioner. I don't use a crank pulley installer. I didn't use an alternator overcharge pulley either because I don't have an anything electrical that causes huge draws. I didn't use any special belts either. Just the belt that came with the UDP and added an AC belt tensioner.
