Couldnt find a reasonable engine, so I installed a 4.3 vortec from a 2011 gmc Sierra. I also used a summett carb 500cfm and 2111manifold. My problem is it tries to idle at high speed. 2 mechanics changed intake gaskets and carb gaskets. With all vacuum ports closed, still have extremely high idle speed. Any ideas ?

I don't think that manifold is compatible with a later engine. Can you elaborate on the manifold? later Vortec engines don't like early Vortec things.
