Hi Alan,

Wight for so many years.
Good point there. But then, your truck is original ;-) Mine is a bitsa
that was taken to pieces and put back together with freshly painted panels,
so most of its olifactory history has been lost. *sigh*

Sorry Alan, don't drink and read then... ;^)

Interesting. I wonder how they managed to do that? Though, I have heard a
couple of recently rebuilt 2.25 lumps that were extremely quiet. One was
just "rebuilt" but the other, I think, had someone go to the trouble of
weight matching the engine components first. Maybe it was serendipity...
On a related subject, the diesel engine in my mercedes 300D is surprisingly
quiet. At idle, it is loudish, but the higher it revs, the quiter it gets,
until there is just a low hum at 70 mph. After a good highway thrash, the
idle quiets down to a low, happy chortle. I know there is sound proofing,
but not *that* much sound proofing (note for wrecking yard divers, this
stuff could probably be used in a rover, especially the thick floormat
deading...). Going throught the manual, it seems that these engines are
balanced and blueprinted right out of the box. The cylinders and conn rods
come in a wide range of weight classifications, and the book cautions that
when rebuilding the engine, to ensure that if any components are re-used,
that new componenst match the ranges. Very cool. I had thought it would be
fun someday to try this with a 2.25 engine, start from the bare block and a
warehous full of bits and start weighing, just to see what the result would
be.
