All oem 90mm tb's interchange?
Are all car and truck throttle bodies interchangeable? Ls2, ls3, l99, later 4 bolt vortecs etc...? What are the functional differences, if any between the 4 bolt tb's? My application is an 04 lq4 w/ a m112 magnacharger w/90mm j-tube controlled by an 03-04 truck computer DBW w/4l80 in a 55 chevy wagon. What OEM tb's will work for me?

The LS2/LS7 have the silver blade. The early LS3's also had the silver blade. After about 2009 or 2010, they switched to a reverse open gold blade 90mm. When I was doing my research before I bought my LS2/3/7 silver blade, about a year ago, everyone was having problems with the gold blade opening all the way up. I would be interested to see if they got that problem worked out like RS/SS said because the gold blade is MUCH cheaper.
