does the 6.0 engine come out with an 80mm tb? or can an 80mm tb be bought at the gm dealer?

 

i think the 80 or 85mm bodies are on the 6.0 HOs.

 

GM only makes a 78mm cable tb or 90mm DBW for the vettes no 80mm tb offered by them or anyone else ot my knowledge

 

BBK has an 80 MM TB.

 

This is correct

 

Yeah an aftermarket company does I forgot about BBK. From GM though which I think is what the question is asking they dont make one in dbw or cable in the 80mm diameter all truck 6Ls get the 78mm LS2s and LS7s get the 90mm units.
