fast 92mm
If you SEARCH most will say 15 or so over LS6. The more cubes you run and higher you spin the more gain as LS6 dies at 6200 or so. I was a little disapointed with my 90/90 but it went on with H/C so I have no baseline. I can say I expected #'s in sig with my LS6 and got the 90/90 for a good deal at the last minute. When I go bigger cubes though it will really pay off and the throttle response is AWESOME
Looks good too! 


just ordered my nick williams 92mm throttle body and fast 92mm manifold...just wondering if anybody has these mods and what kind of numbers did they put down?
