We would like to buy either a 3.8 or 3.6 bolt on pulley that fits the zzp mps hub. We dropped to a 3.4 but its too much until we tune and get headers

 

LOL, been there, done that too! I bought a used 3.8 on fleabay for $10. I think his name was fastfieros or something.

 

I just checked there but no one has any. I'm thinking I may get both if I can find them cheap

 

Just ordered a 3.6 from zzp and I may not need the 3.8. I'll know as soon as I install the 3.6

 

Good luck with it!

 

Thank you. I'm hoping the 3.6 will get us down to the kr we had before adding the rockers and 3.4, which was 2-3 at WOT, but it only happened right before the shift so most times I could avoid any kr at all. If not then I'll go for the 3.8, lol
