Throttle body question...
Hey everyone, a quick question. I just put an LS7 throttle body on the LS2 in my Trailblazer SS and I was wondering if anyone knows if this throttle body (the LS7) will fit the LS6 engine in the C5 ZO6?? OR if it should even be done- unsure size of the LS6 TB... Any help or info would be awesome!

I was under the impression the LS7, and LS2 had the same TB, @ 90mm. The stock LS6 TB (and intake manifold) is 78mm, and is not interchangable, as it only has 3 bolt mounting, versus 4 for the LS2-7.

Thanks for the input... To my knowledge the LS7 is a 90mm but it does not have the "lip" on the leading edge of it as the LS2 does- on the Trailblazer SS forum they were seeing dyno results of 3-5hp, not a big deal but it will help with forced induction which I am thinking of doing.
