OK, I stand (sit) corrected, I guess. PineyCruisin bought a really nice van with a V6, which I would have been loathe to do. However, in researching some more, it appears that there are some satisfied customers out there:

[font=Arial, Helvetica, sans-serif]"Sorry to hear of One-Shot's problems with the 4.3. I have a 2003 Savana [/font]
[font=Arial, Helvetica, sans-serif](7,200 lb GVW) van with the 4.3. I only have had it for 18 mos., but it [/font]
[font=Arial, Helvetica, sans-serif]has been a great engine and great vehicle so far. I have had zero [/font]
[font=Arial, Helvetica, sans-serif]problems with it, it has never been back to the dealer, though there is [/font]
[font=Arial, Helvetica, sans-serif]a recall to replace the rear license plate light (since when does a rear [/font]
[font=Arial, Helvetica, sans-serif]license plate light merit a recall?).[/font]
[font=Arial, Helvetica, sans-serif]Most of my driving is in Los Angeles traffic, but I did monitor my gas
mileage on a 1,000 mile round trip on the freeway, and it averaged 20.3
MPG with less than 2,000 miles on the odometer at the time. I have not
checked it since, but I have to think it probably is even better now
that the engine is broken in.[/font]
[font=Arial, Helvetica, sans-serif]The 2003 4.3 passes smog here in California as an ultra low emission
vehicle (ULEV) even without an EGR valve, which should stand a testament
to its efficiency. Here are a couple sites with some info/specs on this
engine:[/font]

[font=Arial, Helvetica, sans-serif]What sold me on this particular engine is that it basically is the
rugged iron 350 V8 with a pair of cylinders removed from the center. As
noted, it is a large bore and stroke engine (like the old V8), is made
of iron, does not seem to have a lot of the cylinder head and intake
manifold leaks that many of the aluminum head engines seem to have, GM
has made millions of them and appears to have refined it.[/font]
[font=Arial, Helvetica, sans-serif]My engine is very smooth (balance shaft and enhanced mounts). But what
sold me on the engine was that it ought to be rugged, it can get 20 mpg
in a cargo van, and it develops peak torque (260 ft lb) at an incredibly
low 2,800 rpm. Right off idle, this engine has great torque, feels like
a large V8, just what I wanted in a truck. I believe the large bore and
stroke, combined with a cam profile, make this engine exceptionally
"torquey" for it's displacement and fuel economy. As a comparison, the
4.8L V8 produces slightly more torque (285 lb ft), but only at 4,000
RPM.. The 4.3 has great "grunt" off the line with no fuss, no muss.[/font]
[font=Arial, Helvetica, sans-serif]Now climbing in the mountains with a load, it only has 200 HP, so the
four-speed automatic will downshift more than if it had 6.0 litter V8,
but it has never been unable to hold the speed set on the cruise control.[/font]
[font=Arial, Helvetica, sans-serif]It has roller rockers and roller lifters, a cast aluminum oil pan that
bolts into the transmission as well, very sophisticated fuel injection
and computer engine management systems, no noticeable noise or
vibration, and great drivability and economy.[/font]
[font=Arial, Helvetica, sans-serif]One-Shot, I am not trying to dismiss anything you experienced with your
engines, but just wanted to offer up that I could not be happier with
the 2003 4.3L in my GMC cargo van."[/font]
