      Throttle body size question

      I have a LQ4 in my 67 Chevelle. LS6 cam, LS2 intake, ported 853 heads, short headers and full magnaflow exhaust. I'm running the stock truck 3 bolt throttle body using a 3 to 4 bolt adapter on the LS2 intake. (I realize this isn't the greatest intake) car runs great, good power and great mpg.



      . Is there ANY benefit to going with a 90 or 92mm 4 bolt throttle body? It seems like there would be but not sure so I figured I'd ask.

      Tighten it till it strips & back it off a quarter turn.
