This is a two part question:
1) I am planning to change my stock pulley out to the 3.4 MPS system and will probably go with the zzp mps and rent their pulley puller to change them out. What is the backing plate, what does it do, and do I need this to pull off the stock pulley or to put on the MPS hub?
2) If I run the 3.4 can I run the stock belt or will I need to get a new belt. If I need to get a new belt, who has them cheap? Any part numbers would be appreciated. I got this part number from zzp's website: 4060660- Is this the gatorback? Is this what I need? Who has it the cheapest?
I wont be doing this until I get the PCM from 3800 so it is still a couple of weeks off. Does anyone know how long they have been out of stock with the 3.5? I want to run the 3.4 but if I am knocking I am going to go with the 3.5.....yes I will get 104's and the pcm before dropping the pulley size.
Thanks again
