Have the injection pump and injector finished.
Turns out I was thinking way wrong about the pump. It's only an A series with the 7mm stroke. And will accept a 6,7 or 8mm element. Corrected the pump by installing the 8mm element rather than the rusty crusty 7mm found inside.
The injector had the wrong tip and a weak spring. The tip was changed to the one used on the PJ series of Petters which works with the same 8mm pump used on both the PH and Pj's. The tip will be a little large for the PH unless we can cram a PJ's 3-13/16" bore piston into an overbored PH wet sleeve. Is so the rack travel will just have to be limited to prevent black smoke.
Valves and seats were a total write off. Somebody had went wild a couple of times grinding the seats deep. And the valves to a razor's edge. There are some new Manley Pro Flow small block chev valves laying around here. We plan on cutting a couple to fit.
I'm having a tough time convincing my machinist to cut that big ugly lump out of the intake port to make it match the exhaust port's shape.
The cam and followers going to be sent out to be trued up as well. The cost is surprisingly low.
12HP without excessive smoke at 1800rpm would be nearly enough to handle the 10KW generator project if we can swing the 3-13/16 bore.
