Getting rid of my 99 silverado sclb, for a 02 tahoe. Both have 5.3l. I have the pigtail for the throttle body, I believe its drive by wire. Will all the other stuff bolt up or were there changes? I have the old two belt system. Will the lower crank pulley work? I'm not concerned with the electronics, I plan to get Edit or Hp tuner. Any info appreciated.

 

The issue isn't the year difference, it is the electronic throttle versus cable. The only thing I can think of that you will need is the elbow that bolts onto the blower (to face the electronic TB forward) and the associated intake plumbing. The rest of the kit is the same.

 

I thought they didn't start using the drive by wire till 03?
