Instead of looking for the strongest or best castings I can find lately, I’m collecting the scrap to experiment with and try things out on. I’m looking into getting into some “Backyard Foundry” activity and seeing what iron I can chop up and melt down to pour the water jackets full on the throw away last overbore sized blocks. And whatever cracked heads, too. Looking at the whole truck and tractor puller mentality of cooling it with a river of methanol poured down its throat. But admittedly, I’m more just wanting to experiment with seeing if a production iron smog head could be turned into a tunnel port (or worse, stacks out of the top of the head, like a sprint engine) design. Cast on another port and next to the pushrod pinch and shape the center divider made from the port wall like a wing where it goes into the bowl. Of course, it would take a custom manifold (and probably a whole lot of unforeseen patience with getting the casting right) to make it happen. But I would like to find out how two ports divided by the pushrod pinch flows compared to one with the pushrod moved over.
