You can put water thru your old cast iron single bbl intake and the Fentons. Make an aluminum plate with gasget couple fittings. The aluminum plate will need to be severly notched on the firewall side to clear the rear fenton cast iron exhaust. Trial and fit situation. Come out of your waterpump to one of the holes in the alum plate then out of the plate to the top heater hose or to the therm. Works for me.
