While you're on the note of motor mods, did you notice if the crank in
the 1725 was steel? Are the rods forged? I have yet to see the insides of
a 1725, and I have pondered aquiering one just for rebuilding purposes,
to know what I would be getting into. I think the alpine motors would
hold their own better if the oil pump was a little beefier. Mine only
pushes 30 lbs at 60 mph, and 15 at idle!
