I am a retired ex/heavy mech. and have worked on my share of Detroits. As I remember the valves are intake and exhaust is sleeve ported direct to manifold. The blower charges the cyl. on the upstroke valve's open and before tdc the valves close and the injector puts in the fuel charge. Ignition and power stroke and at the bottom the exh. is released out the port. Getting the pressure from the blower and how much would be the hard part. You can put a carb on it to get away from the injector's. As mentioned also you need separate oil supply and pressure or some other type of lubrication.
Model glow fuel would also work and I have run 65% nitro while racing .40 size. I have also used nos but that is another story. Just be advised my luck was out of sight rpm for a few seconds before it blew.
To me if you can get a blower or make one that will put some psi out it would be easier to get it to work as a Detroit style 2 stroke especially in the 6/71 category.
