Well my cousin is wanting to upgrade his throttle body on his truck which is a 06 4.8 from the stock 78mm to a 90mm which would be a good throttle body to buy? His truck is a full bolt on with cam,stall. Any suggestions as to which way to go would be great thanks!

 

The NNBS trucks are 87mm. And I believe those are better to use than the LS2 tb because the blade moves a different direction or something. He would still need an x-link I believe.
