I was wondering what was the most relieable chevy diesel after 89? What type of MPG they get? and how big are they comparison to a ford 302? I was thinking of swaping in a chevy diesel sense they are cheap and pretty light for a diesel. Any info would be great!

a decent 6.2 would be the best bet. They are reliable as a Chevy can be, and stupid simple, but dont expect real power (you can tune them for gas mileage though!!). Light is kinda a condtradiciton in terms for diesels, I do believe 6.2s are big block Chevy heavy, not anywhere near a Cummins, but still.......................

thanks for the info thats what i kinda thought. Yeah my cummins in my dodge is 1000 pounds! i want to put it into a Bronco II i have and i have put a 302 in one before and i want to build a new daily driver so the chevy's power would be pleanty powerful. Are these engion really large?

Size-wise, I'd say the 6.2 is definitely larger than a 302... it's smaller than a 460 or 454, but not by a whole lot.

Well i have know of some people putting 460 in bronco II so i think i could fit one in. Do they come with duel sup pans?

Check out this place. It's the best Chevy 6.2 / 6.5TD site I've found. Just scroll down to the 6.2 and 6.5 forums.

Not sure, but I think you can get a 6.5TD with mechanical pump in up to 94

Stay away from a NA 6.2, there are even bigger DAWGS than the 6.5TD. If you buy something pre 97, you wil lwant to upgrade to 97 + cooling sytem.

You can get a solid 6.5TD to 300RWHP with bolt ons. ( Injectors, exhaust, pump mods, intake, intercooling, and a few other tricks ) but you'll never be in the same league as a Cummins or PSD.

Anyway, check out the site and read the FAQ in both 6.2 and 6.5

i would go with a 4bt cummins ... alot of them came with chevy adapter plates so u can run your tranny they weight alot less and they make alot of power and good fuel economy. i just purchased one for my buggy ill try to put some pics. up soon

The cummins 4cly wieghs over 750 pounds wich is more then a big block chevy if the chevy 6.2 wieighs less then it would be good, i was going to swap a cummins in there first but the cheapest i could find was 2500 and i dont feel like spending that much on just the engine. Its going into a bronco II which wieghs next to nothin and should be running 33's and be my daily driver i just want something reliable and gets good gas millage not looking to crank out alot of power. Is the 6.5 pysicaly larger then the 6.2? Thanks for the info so far!

i havent weighted my cummins yet but i was told that it weighted a about as much as a small block 350. also i have saw complete bread trucks on the net for as little as $1000 dollars with running motor and tranny.. they are out there u just gotta look for the deals

Yeah they wiegh no were near a small block chevy. My 6 cyl cummins weighs over 1000 pounds and the 4 cyl is basicly the same thing with two cyl cut off. If you know of any around me in CA i would love to know about it every one i see is way to much and i really dont want the whole truck thats just a pain in the butt did that for my dana 60's in my crawler.

A 6BT Cummins dressed and wet is closer to 1200lbs.

i can belieave it at least the 12v i know thw 24v is a little lighter but still a heavy mother!

:D hands down!!
but i'd go for the 6.5. had mine for 4 years and it kicks ass! its NA which knida blows but does fine for me. u never have to worry about driving angles, it will run on its side (know from expirence.) take pics and post!

The 6.2/6.5 engine weigh about the same as a 454 with the overall size similar to a 350. You can spend lots of money building up a 6.X engine to produce as much as 300HP but it's costly.

If you can get a 6.2 with block casting ending in 599 (early 90's) and some 6.5TD 97+ heads, 2000 stock 1 Ton cooling system, marine db2-4911 injector pump and injectors you'll be laughing, use it in either a non-turbo or turbo format. A very sought after block is from 82' era and is painted orange, this one has a higher nickle content ... bolt all the above to it. If your on a budget any stock 6.2 will do fine. Try for the above mentioned blocks, only the 6.2 with 599 block cast can be bored to 6.5 size.

Here are some upgrades for you to look at

I have a fairly mild N/A 6.2 in my Blazer that's a trail only rig and am pretty pleased with it. Granted, when the time comes it's needs replaced I might opt for a gasser engine, but as of right now I really have no big desire to replace it. As mentioned it's dirt simple and has EFI-like running characterictics on the trail.

With a very average 34:1 (auto trans) crawl ratio and 38" tires it crawls rocks really good and has only needed very mild throttle to make the tires spin when wedged up. The low speed responsiviness it has is great, and it still has enough power to push the 6,000 lb. truck with 4.10 axle gears and the 38's to 70+ mph on the freeway. I can also spin the tires in 2nd gear low range in slippery stuff without much issue.

Now don't get me wrong, a nice 300 hp small block gasser would be cool to have and provide a lot more power........but right now I'm pretty satisfied with it. I would think in a small vehicle and with a little work it would be a decent engine in a trail vehicle, and as already mentioned it's a lot simpler than just about any EFI setup you can think of. Heck, it will even run a long, long time with a dead alternator if you don't stop it and restart it several times.

The 6.2/6.5 engine weigh about the same as a 454 with the overall size similar to a 350.



Not true. The 6.2 / 6.5 is a lot bigger than a SBC since it was based upon the big block Chevy and it is heavier than the BBC. From personal experience, the BBC wieghs in around 600-700 lbs and the diesel wieghs in at around 850 lbs....

6.2/6.5 NA weighs about 650lbs. 6.5/6.2 have no relation to the BBC other than approx physical size. It was designed in every way to be a diesel. 599 blks are good or the latest versions from navistar are the best in strength. The navistar versions have more nickle content and were beefed up in certain areas to prevent the blks from cracking. 1994-2000 blks are the weaker blks. All 6.5/6.2 blks can crack in the main cap webs and they would spread to the lower part of the water jackets. You should pull the center 3 main caps and look for cracks originating from the bolt holes. This area is the most common place for cracks to occur but all long the webbing can be suspect.FYI

my 6.2 is 379ci and weighs around 700-750lbs.
