Can't believe you tore your motor down to get us that picture. Damn nice of you.this is the underside of the pre Vortec 4 bbl intake, notice how the water passage is only up at the very front under the thermostat housing, the Vortec intake has a much bigger water passage under there. Maybe more places for water to hide....
