Frenctownflyer,Its a flathead but I can tap into the road draft tube or remove it and place an freeze plug etc, in its place and pull the air back thru the oil-filler-breather-dipstick; (which is a combination on this engine).Wonder where to get the vacum? Possibly the intake manifold itself? I think this engine is only about 228 cubic inches or so. Very small displacement for such a huge chunk of castiron.Worst thing is there was nothing wrong with the fuel pump as far as I know till he decided that it needed to be rebuilt?
