does anyone know what the difference is.... I have no experience with diesel but do know that they're much easier to find. Is it possible to use a diesel block bolt everything off my existing engine and run it like that... or is that just not going to work?

 

Nope. Don't even try, completely different engines. No parts interchange.

A whole diesel motor in your car would work, but still, bad idea. Leave 'em for the trucks.

 

Just not going to work.

A diesel engine uses a high compression ratio to heat the air in the cylinder above the flash point of the fuel, which is injected into the cylinder directly when the cylinder is to fire. Also known as compression ignition engines. Diesel is a thicker fuel, with a higher flash point than gasoline. There is no ignition system. Because of the higher compression pressures, diesel engines are beefier than a similar size & power gasoline engine.

GM made a diesel out of their Oldsmobile 350 gasoline engine, it was basically a disaster because it simply wasn't beefy enough. It was replaced with a blank-piece-of-paper designed 6.2l, which was much better.

 

Well, I wouldn't call it 'much better'

It's the only diesel besides the 350 diesel that will bring the value of a truck down

 

I'll take a 6.5 non-turbo diesel anyday of the week. The ones I have dealt with are pretty reliable. I still see 1-2 a week with over 300,000 miles on them.

 

This has been brought up before, and it's a waste of breath.
Lets just leave it at ; a diesel motor is completely out of it's element in a 3rd gen, **sports car**.

No parts interchange between engines.

 

I have a engine builder down the road from me that used a oldsmobile 350.
He used the block and built it as a gas engine. They can be bored quite a bit. He built it for a circle track racer that was restricted to a 350 block.

They ended up with a 4xx cubic inch motor. I beleive it ended up being a very strong motor. Like I said, he used only the oldsmobile diesel block.

 

Awsome, thanks for the pointers...I guess I knew about them not having spark plugs etc, but hoped someone would say I could use the core and take out the glow plugs for sparks... but if not thats fine too... I definatley don't mind workin on a gas...besides it smells better hahahaha

 

the olds 350 diesle was in cars and trucks both, from 78-85

had a few of them myself, most recently an 86 caprice wagon and an 81 c-10 pickup, both vehicles i stripped for parts and stashed them away

they are pretyt interesting, but theres lots more extremely wierd engines that GM made over the years than these common diesels



good luck

 

All i wanna know is if it is possable. what kind of transmission it would need and what blocks would fit in a third gen. just out of curiosity. i have no interest in doing that kind of engine swap just wanna see it done
and if soneone can do that, i wanna see some burnout videos!

 

Like bluegrass says it's fully possible to use a diesel block to build a super heavy duty gasoline engine. It has a beefier bottom end etc. If you Google GM 350 V8 Diesel I'm sure you'll come up with some information about it.

 

Here's a diesel Vette: The Diesel Page, Readers Rigs

I consider it a travesty and there's probably a special place in hell for this guy, but you wanted to know if it was possible... The answer is yes. If you can do it to a Corvette you can do it to an F-body.

 

The 350 Olds diesel block is seriously beefy. It can be safely bored .125 over for monster inch smallblocks. The motor as a whole had bad head bolts and an inadiquate head gasket which often failed. Head studs and better gaskets make for a much better motor that can actually handle some boost if you were to fab up a turbo setup.

 

Hey! I have an Olds. 350 diesel in my 1980 2 door Pontiac Bonneville. If you're bored and want to know more about the Olds. diesels, 4.3 V6, 4.3 V8, and the 5.7 V8 just go to olds-diesel.com

 

I've got a nasty 5.7 diesel in my 80 Cutlass...

It may find it's way into an f-car before it's all over...
