I thought the Vortec manifold outlets were in the same place as the TBI manifold outlets.but they wouldn't bolt to the tbi exhaust. you'll need to get the whole vortec system.
Am I wrong?
on over 8600gvw trucks there's no heated-air intake. beats me why.
But your C1500 would not have a greater-than-8600 pound GVW rating.My 350 has a heated air intake, 92 C1500
