Previous health issues had put this on the back burner. Now slow cash flow is slowing me. I should have the car/engine project complete by spring.
During my "health crisis" I did have plenty of time to think this thru. The biggest thing is preventing a water shortcut between the inlet at the face of the head and the water crossover. Simple freeze plugs there resolve that issue. Water has to flow across the head to the rear "exit", which wiil be hoses located where the heater nipple and rear freeze plug usually go. The hoses will get plumbed forward to the crossover so water can get to the upper radiator inlet. I will tap the existing holes for a pipe fitting (likely either 3/4" or 1" pipe id, I dont want restriction there). I may not tap into the actual crossover because there is an aftermarket part for SBC's (that fits under thermostat housing) available already made with provisions for water lines.(Moroso I think)
Water in block will still behave as it did in 55-59. (see timing cover pics) I see no reason it shouldnt work better than the 1960-up cooling scheme.
