Whats the largest throttle body for this intake? I have the Gen IV 6.0L LY6 truck motor and I'm wondering if anyone knows what size throttle body it has from the factory? What is the largest size throttle body I can run, 90mm? Here is a picture of what I have:

I am pretty sure they are 87mm. Not sure about running a 90mm. This is the throttle body:

It was used on a lot of engines, including the LSA engine. I doubt that going to a 90 will make any difference. Just run the stock one.

The stock throttle body was a 87mm, a 90mm LS3 throttle body will bolt right up to it. Now going from a stock 87 to a stock 90 will not gain much, possibly 3-5 hp, if that, once it is tuned for the 90. If you do not have a throttle body, I would go with the 90mm.
