what size throttle body does my 8.1 come with, and if it fits the 4.8,5.3,and 6.0.. I would imagine it would fit ..unlees mine is bigger from the factory..

Someone mentioned 'retune' i dont think you would havr to adjust tune for sucjh a minor upgrade..

When i asked justin about tuning for shorty headers he said no, but yes for long tubes..

 

 

 

None of the LS throttle bodies will fit your truck. Your engine uses the old-school big block design that is completely different.
