Stock F-Body throttle body or stock 6.0 throttle body? I thought the LQ4 and LQ9 had an 85mm TB. Seems you would gain something seeing as you have more cubes and you have better flowing heads.

Default Throttle body

The throttle body i have now is a stock fbody 78 mm throttle body.BBK sells an 85mm throttle body so i assume it is close to that.I would like to find a 90mm throttle body but cant find any 3 bold style 90mm throttle body.
