There's nothing you can do to hurt them except not keep them full of
clean oil and filters, and never, ever, ever over-tach them. Other than
that, they're bullet-proof. You _cannot_ 'overtorque' them unless you
LUG them -- so long as they maintain their set speed, they are working in
their 'reliable' realm.


I think that at this point in time, the market for them is entirely
driven by nostalgia, not by money making or convenience
considerations. Whoever specifies one for their boat do it for
nostalgic reasons.

Custom coach builders are still using them as if new engines! There's no
'nostalgia factor' in picking a solid, bullet-proof motor that will go
300K-500K miles!

Would this pass emissions tests?

Think about this.

Let's say that you install this engine into a bus or medium truck. You
would get, say, 8 MPG.

With a newer, more efficient, engine you would get 9 MPG.

This means that if you drive 60 miles in one hour, you would pay for
about one extra gallon of fuel. Say $3 per hour.

If you drive 10 hours per day, you would spend $30 extra per day on
fuel.

If you drive 250 days per year, you would spend $7,500 extra on fuel.

Over the expected lifetime of 500,000 miles, you would burn 56,944
more gallons of fuel with the Detroit as opposed to a new engine,
which is equivalent to, say, $170,000 dollars in additional costs.
