Hey guys, I am away from my car and I'm wondering if anybody knows the bore diameter of the stock intake where the throttle body connects, I know the throttle body is 90mm but what is the intake, also I guess I'm asking can I go to a 102mm TB or is the intake diameter smaller then that and I would have to change intake thanks :wink2:
There are no intakes for LS3 that out perform the stock intake.
A larger throttlebody will do virtually nothing to help you with power
you can port The original throttlebody and pick up a little bit but it's probably not worth it
