Yes, they're much smaller.  My impression is that they were used on most
or all 6.2L diesel trucks.  They were used on some late '70's & early
'80's large GM cars too, but I don't know which ones.  Maybe just the
diesels.  The size is attractive because my engine compartment is much
fuller with the 6.2 than it used to be with the 196. :)

btw The 196 is still available.  I'd love to get it out of Mr. Scout's
way.  It runs fine but one cyl has only 75psi compression.  It uses _no_
oil, though, so I tend to think it's a valve, not rings.

I just took it on sort of a "maiden voyage" to the store last weekend. 
:) I haven't been getting it done very fast, too much other stuff to do
etc., but there are just a few rough edges to finish up now.  OK, some
of 'em are VERY rough. :)  The engine works great and seems to move the
rig along just fine.  The trans (700R4)  shifts slow and slips if I step
on it too hard, so I haven't been able to open it up and see what it'll
do.  I guess it sat too long without fluid and the seals dried up. 
Hopefully it'll get better with a little use and I won't have to rebuild
it right away.

There are probably better diesel engines to use in a Scout, like a
Cummins 4cyl turbo, but those are a LOT more money, and 6.2 parts are
everywhere.  So far my only regret with putting in the GM 6.2 is that I
didn't get it finished a lot faster.
