63mm throttle body and injectors?
Help me clear something up.
By using a 63mm throttle body from Leigh performance and Ford 5.0 Mustang fuel injectors I will see big gain in my 4.0?
By the way this is a great place and love the photos.
And do you have to change or do anything to put the injectors in ?

The bored rb will inprove throttle response. As stated above the injectors aren't a big improvement if you don't do the intake manifold upgrade from a 99 or newer XJ.
