The Stovebolt Site Forums The Parking Lot Big Bolts 6.2 diesel in 1952 chevy 2-ton

has anyone put a 6.2 chevy diesel (1985-1987ish) motor in a 47-53 chevy two ton?, would it be the same as a gas v8 converion? and what kind of trouble would i have to go through to get it done? thanks

I have not seen one done.
Yes, it should be just about the same as the V8 gas conversions.

While many people have good luck with the 6.2 and 6.5 diesels, I hear a lot of people who have problems, or just are not impressed.
If you do this conversion I would recommend you use the latest turbocharged 6.5, they are stronger and much improved over the earlier ones.

Why do you want to do this conversion?
What do you want to do with the truck?
Have you considered more powerful engines, like the Duramax, or a 7.3 ford / IH?
Or even a Detroit?

Grigg

i agree with grigg totally. the 6.2. and 6.5's were an anemic p.o.s. and never were much of an engine. with all the experiance g.m. had with diesels, and being the authority in domestic diesels for decades, that they ever did those engines in the first place tells me crack addiction started much earlier than it was reported. g.m. lost a ton of money on those boat anchors.
the 7.3 corn picker engines are very reliable (just stay away from the turbocharged later non power joke version--head gaskets) are economical, and pretty esy to maintain, while not being expensive to buy. do the pump timing and up te pressure 105, along with banks injectors, and the thing will perform much better than stock.

HOWEVER!!!!!
grigg did the ultimate kick-a$$ detroit swap, and i would certainly consider that as an option.

nuthin like a 100 mph diesel bolt making folks scratch their heads!!

I agree w/Grigg (Hello Grigg).

I had an '84 6.2 1/2ton truck a long time ago. I loved the truck and liked the mileage, but even for a light weight short bed, it was gutless. I hated the engine.

Grigg made a good point on the 6.5. Better performance and it has a turbo. Most of the 6.5/turbo trucks that I have been in are dogs as well. I know a guy that removed the electronic pump from a 6.5 and swapped in a mechanical pump from a 6.2 (w added fuel delivery). It ran respectable.

In all honesty. W/all the masses of Cummins trucks that have been produced over the years, that would be the better choice.
I purchased a complete 03 Cummins engine with tranny and electronics for $1500. With a simple programmer, it'll easily be good for 600+ ft.lbs. It'll eventually make it into my Longhorn.

The old Chevy/GM diesel combo would be cool, but it'll hardly be able to pull its self down the highway.

If you plan on doing any towing duties. Get something equipped w/a turbo.

yep...... good advice

Keep in mind that a diesel like the 6.2L or 6.5L usually has a sweet spot around 1800 RPM, much lower than the stock truck engine would have.

For best results, gearing changes will be needed.

I am thinking about eventually putting a diesel in my 1967 C50, but it would be a long ways down the road...

To deal with the gearing issue I am planning on installing an divorced NP205 transfer case backwards to act as an .5 overdrive. This along with my SM420 and two speed rear end should give me plenty of gearing options for either a gas or diesel engine, and handle cruising at 55-60mph.
