Have any of you LS2 guys looked at doing an LS7 throttle body? They appear to bolt up and have better machining. The pics I have seen & what I have heard they have more factory machining and appear to be kinda polished versions.
I did get a slight whistle. I thought I may have had an intake leak but if you have it too maybe not?
The part number is the same for the LS2 and LS7 throttle bodies.....12570790. The machining difference may be a sourcing issue from a different vendor. Mine was not machined except in the throttle blade area.
I don't have a whistle but then again, my setup is N/A.
