detroits were designed in the 1930's before GM owned them, they're not actually a GM designed engine, or else it'd be in the same boat as the 5.7, 6.2, and 6.5 diesels.... I've seen a 6.6 clean house at the truck pulls 2 years in a row, after the second year it warped the heads soo bad they were trashed. Yet I see powerstrokes pull through the gates numerous times with no failures. just what I've observed. I don't preach IH for the good of my health, or because they're cheap, I'd be a Rich man if they were cheap to build!

April 1937: the company was founded by general motors as the detroit diesel engine division. Its initial product line was the series 71 engine family, consisting of exclusively inline configurations ranging from one to six cylinders.

They must have had a better engineer back then, surprising to see one of their engines that not a piece of garbage! I guess my sources were wrong, I was told detroit diesel was their own company, later bought out by GM.

Anyway, this thread needs to stay about what subject is about, or what can be swapped into a truck.
Just curious jon, you worked at a GM dealer for 3 years, and seen duramax engines failures there and at sled pulls. Which is it?

Hey bubba- we've all got opinions and personal preferences. But your comments and tone are disturbing the sanctuary of the ihon forum vibe. You know this isn't pirate right? Check yourself.

First in the realm of diesel power plants non are more well known then the detroit/GM 2,4,6,8,10,12,or 14-71 series 2 stroke's and their world famous roots super chargers. If one can be respected when writing recommendations on ihon one ought to learn some details on the subject before becoming a self appointed expert.

Second: the duramax series of engines was designed jointly by isuzu and GM (GM had very little influence) based largely on isuzu 's massive experience in the mid and heavy truck world to name one. Npr ring a bell? My feeling is that GM had weight constraints and the aluminum head addition

I know for a fact that the first thing guys did was bump up fuel and manifold pressures. I did a lot of work for banks engineering so believe me gayle and I have had a few discussions on that exact subject. And many more on k boats and hydroplane racing. Anyhow got off topic for a moment. Why make a blanket statement about GM engineering when it was isuzu that designed and built the duramax.. The duramax in fact has become a very very good engine and probably has a better reputation than the power stroke (IH). Banks has used the duramax as its core for high performance marine and racing power plants. Do some reading... banks power - marine diesel engines


1300hp duramax with aluminum heads banks sidewinder s-10 - video - jay leno's garage


I have watched these things be put through a grueling torture in the banks test cell. Basically max power at max temps for 1 week non stop except for service.


I think everyone needs to be open minded, respectful here and do some research before making statements . After all I believe most want to learn a thing or two before we take on out projects...

Whoa I feel like I'm on the binder planet, ok forget it I'll stick to what I know and have learned over the years, to each their own. My friend has a fleet star with a 6-71 and it's awesome it really moves along quite well. The duramax is quite powerful, and runs good, but (in my opinion) doesn't have the longevity as the other diesels on the market (stroker, cummins). Some have had better luck than others, I guess, mabe nepa got a bad batch.... I'm assuming GM paid banks a pretty penny to promote their engines, just a guess, I know if someone paid me some cash to build a 350 and make it have 800 horsepower to promote it, heck it's cash in my pocket I'll do whatever they tell me!

Anyhow I located a 4 door IH pickup for a dt466 IH pickup, I'm waiting for some more pictures before I purchase it, people said a 6.9 would be too much for a Scout.... it works quite well!!!

I don't think gale banks was paid to do anything with the duramax. He's an aftermarket guy. I agree with Robert, duramax's probably do have a better rap compared to the powerstroke, probably because you can hot rod them more then the powerstroke.

Again, nothing could be further from the truth. Gayle has built his marine diesels on the foundation he felt was the more up to the task. He has literally millions invested in the project so to put that kind of money in a new product and not have full confidence in the outcome is simply not the way gayle works.
You need to know him to know how he works.

The racing part being the test bed and advertizing tool that it is would be where the f'you money is. If a green hand shake was given anywhere that is where it would be. Keeping that in mind GM has pulled most of its racing funds out of programs since their financial whoas and bail out. I can't speak for ceartain about banks in the racing sponsership sector so take it with a grain of salt.

I'm not a diesel fan...I got no dawg in this hunt.

But I was present during all of the development of the duramax version of the world-class isuzu v8 motor and saw first hand how the "parent" (and the parent is not isuzu) can really cheapen and foul up a motor during development for the u.s. Market. This was done in a skunk works r&d facility in cerritos, CA over a two year period before the "duramax" version was brought to market in it's first gen guise.

My role in that project was to prototype an a/c compressor system for that engine which GM ultimately shitcanned in favor of a much cheaper alternative. The major player in my former company was isuzu so I was working on this with isuzu engineers at their bequest.

I can tell stories about the development of that motor for hours. Banks had nothing to do with development of that motor during that time. The secrecy of this development project went well beyond the norm for prototype development, and most of that revolved around the emissions issues, along with major durability issues that cropped up during the "cost reduction" exercises. The only place I was not allowed admission into was the emissions lab in the facility, that was because the emissions shit for the "future" diesel stuff was still a moving target from the feds and nobody knew what the future was going to bring. I did all my work after the vehicles came out of the lab in completely disguised 1985 model year chev dually test mules.
