I'll have to ask one of the diesel mechanic's I know for a couple of old
injectors. Then I can try to test them to destruction.

That could be worth a shot, I'll look into it.

As far as I know the differences are in the ignition curves. You can jack up
the timing a bit more on LPG at higher revs.

The thing I like about LPG is the fact that you can run up to about 14:1
compression and the extra torque it give at lower RPM's. Plus the fact that
LPG is worth about 2/3 of gas.
