CH>Im looking at the Chevy 350 for a couple of reasons.  First, they are

Craig, I once did a VW engine to power the generator, which I had
altered by trashing the regulator, and using a low ohm resistor
shunt to exite the field windings. Got 25amps all day @15 v.
However, the low RPM also got me low oil pressure, and the rings
did not like that, wearing out prematurely.
I have since learned that they make internal combustion engines
with a single cylindar, water jacket, and huge flywheels which
run very slowly very smoothly forever. used to power pumps in oil
fields out beyond the power grid.  There are a lot of them in
southern Indiana & Illinois, where there were small wells that
were only profitable during the height of the oil crunch.
The engines can be adapted to run on whatever the pump is pulling
up outta the well and do it very efficiently.  With large bores,
long strokes, and slow speeds, the combustion is complete.
