Well after ALOT of research on all this, I decided to go with the 50mm instead since its recommended for the 5.2. Found a guy that rebuilds stock throttle bodies into 50 & 52mm. He also does other sizes to and they are great deals! PM me if you want to get the info for contacting him.
Just sent the money so it should be here this coming week sometime! I'll post pics and update this thread to let you all know how it does!
