Yes, "TwitchKitty" there was a V6 conversion and Chevy used it in their small station wagon. Used to see them on the side of the road all the time.

My Powerstroke 7.3 (direct-injected) is an excellent engine, despite the rather slow acceleration and 15mpg average..but with an SUV, who really cares about fuel economy? It simply rules whenever I need to tow anything. Just last week I had to tow away 1000+ lb of waste glycerin, and the Excursion didn't even bother with the extra weight.

The engine has 100k on the clock and has NEVER had any major issues, injectors and glowplugs are original, etc. Best mpg was 17, coming down the mountain from Tahoe :D

one would hope a 1000lbs doesnt work your ford My 6.5 Chevy tows 1000 lbs reguraly with 197000 miles on her I just love my old stuff

There were NO GM Diesel "Conversions". They were all designed as diesels from the ground up. They only look like gassers because they are all internal combustion engines!

If you go by the look argument, then you might as well say that MB converted it's gassers to diesel as well.

Doesn't this 300D look like this 250?

Forced induction,

You might check the old 350 GM Diesel that was out in the '70s. As far as I remember it was a 350 gasser block with a 4 bolt main. It was crap from the word go and never got any better.

I met a guy in Austin, Tx. in the '80's that drove an Olds Diesel. He said that he had had 4 Diesels engines in the car and that GM had replaced each one without any problem. Apparently GM knew that had stepped in it when they made that Diesel and made no attempt to shirk their responsibility.

It's not a conversion. It's block is unique and not shared with anything else.

The block was beefed up some to take the extra stress, but never enough.

They stunk, started hard, had constant problems, and smoked like a bad tractor when you accelerated. Gave diesels such a bad name that Mercedes pulled their diesels from the US market.

Many shops were converting the diesel cars to gas engines, you could buy the diesel cars for near nothing used. Fortunately for GM, the bodies and everything else on this era's Detroit offerings were only good for about 3years, so there wasn't much loss when the diesel engines expired early.

Dark days in Detroit.

The little V-6 diesels that came along toward the end of the 350 diesel's massecre was a pretty nice engine, cleaner and pretty powerful, GM liked to pull out of things just as they were getting it right.

the pre 73 chevy V8 is the gold standerd of hotrods
it took many years to get back to that level in the ls/lt V8
and stupid GM gave up on RWD cars at the time they got those good V8s again
in fact GM has a long history of killing products just as they get them right
did it with the early diesels again just as they did with the corvair
65 up corvairs were good cars with crap drum brakes
they fix the brakes by switching to disks and killed the car shortly after that [post 65 vair's are the poor mans Porsche] I had 6 all under a 100 each, it was cheaper to replace the car then do a simple repair in the 70's thanks to the bad press, but they were and are good cars
kill the F -bodys firebird and camaro just as the alloy V-8 came good
killed the fiero after 88 when it was good with the 88 only brakes [vented] and revised A-arms that killed the bump steer also 88 only
GM kills them just when they come good
that looks to be a CORP policy that may well kill GM

btw I agree on the slant 6 mopar sure got that right

The corvair could have been a good car
but,
too little, to late,

pain in the neck to work on, real hassle to put all that tin back on.
and not putting it back prematurly ended a lot of engines

funny thing is my sister bought a corvair because everybody she knew kept saying how good the VW was.

She thought she was getting an american made VW
She thought it would be easier to find parts and service for an american car

at least when she got it payed off she got it right, her next car was a 67 Firebird

Race engines in the 60's? When the old firedomes got hard to find the 426 hemi was the one to beat.
