the Vortec 4.3 used a big upper intake manifold and a non Vortec had a throttle body on it

do you have the truck or the engine and are trying to find out which it has ?

I have the original engine and have brought what was advertised as a vortec 4.3 v6 but it's completley different and does not fit.
Expert:  Gary replied 10 months ago.

can you upload a few pictures of it especially the intake manifold ?
