Algon made injection for all kinds of engines especially the ones Hilborn would not do. I notice this one does not have a pump. Al normally converted Cherry-Berrel pumps from surplus military and installed adjustable returns so you had no bypass "pill" holder. His nozzles were also a little different.
I have converted both of mine to Hilborn/Enderle style. I like Enderle nozzles. I see the "buy it now" is pretty high for what is there; might be the minumum. The tubes look to be quite small so it would be best for gasoline. He had a great design for his barrel valves.
The only thing I disliked about his design was the manifold it self have the exhaust and intaports on the same manifold adding heat to the intake. If you were to convert this for the street with electronics it would be trick and work great....Good Luck......JD
