Hi,
This is kinda boating-related. Anybody hear of anyone who's converted
the Venerable GM 4.3L V6 to diesel? I'd like to do that in my van. I don't
see any room for anything other than a V6, and would like diesel.

Lloyd, the predictable response, of course, is "don't do it". Why?
GM themselves conducted this experiment on a grand scale back in the
70s when they attempted to take an Oldsmobile V8 gas engine and
convert it to diesel. It ran - for a while - but not nearly as long
as most people hoped. It was a reliability disaster since the block
was not really designed to take the compression loads and heat build
up associated with diesel service. There's a reason that diesel
engines weigh more than gas for comparable horsepower.

Why not do something really creative and create a hybrid van using a
smallish diesel to drive a generator, which recharges a battery bank?
