So hit a stump on the road yesterday after cleaning engine and prepping it for new intake manifold that I got for free when I got my 92 sierra so didn't think of checking it make sure it would work with the 94 5.7 since 87-95 all the same right? so I go to test fit before adding the rtv silicone on outer edges and find out I have a 96+ intake manifold for the tru vortec engine. well guess now just clean and paint old manifold and put it back on unless I can sell the one I got and get one for the engine I got. Anyone have one that would like to trade
