4.7 engine Q

I was just checking out my engine and planning my mods. Looks like the TB
is wayyyy too small!! The TB on my 99 trooper was huge, and the TB on my
Impulse is about the same size. I have found one source for bigger TB's,
but I would like to contace a couple more if possible. Also, what are the
sensors attached to the 2nd or 3rd spark plug/coil assembly - there is one
of these sensors on each side of the engine with no wiring going to it.
There is a plug where it looks like a 2 or 3 wire connector could be
plugged in, but nothing... Just curious. Also, since this in an OVC
motor, is there any chance of a rocker upgrade?
Last Q for now... What is the maximum tire size I can install without a
huge lift? I have been successfull in lifting the Durango a few inches in
the front (5 minutes with a big open end wrench) and the rear with a
lowering kit for a chevy ($19). I would like 33X11.5's if possible! If
anyone has bigger tires, do you have a picture?

Thanks a million!
