TBSS Intake, TB, Fuel rails into 2003 5.3L Silverado?
Does everything just swap over and plug right in from an LS2 TBSS to a 03 5.3L Silverado?

its not a direct swap. the 03 and eariler fuel rails have 2 lines. a feed and return. the tbss only has a feed line. its fairly easy to adapt the 03 fuel rails to the intake though.

you need the fuel rails also cause the top of the intake is wider. of ourse you need the intake and t-body and you need an adapter to run it. speartech and torquerush makes them. intake gaskets and bolts are the same.
