Anyone gone with a diesel - The 1947 - Present Chevrolet & GMC Truck Message Board Network

theside00 · 08-02-2007, 01:14 AM

I was wondering if any of you guys have thrown in a diesel? I got a 454 bored out .030 but was wondering if anybody has thrown in the duramax or 6.5 or other diesels. I have a K20 so probably would work better for the 4x4 guys but lets hear if anybody has done this.

**special-K** · 08-02-2007, 05:49 AM

I`ve seen the 6.2s and 6.5s put in a few trucks.One was a guy that had oredered his`71 when new.Around 1990 he refurbrished the truck and had a 6.2 swapped-in.He just recently sold it.I have experience with these motors and would like to put one in a`72 I have.All I can say is if you can get a complete set-up to change over for cheap to nothing,it`s worth it.You won`t be "dropping" a Duramax into one of these trucks,though.It would be alot of work and e-x-p-e-n-s-i-v-e.They don`t share the common configuration that the Detroit-Allisons do and are fully computerized.So,1/2 the wiring and the transmission will need to come from the Duramax donor.

I saw a diesel swap on PIMP MY RIDE. They put the DURMAX in a impala. The car ran great. Had the car running on BIO-Fuel. The car out ran a Ferrari in 1/4 mile.

Thats funny you mention that, I actually work for the guy that did the swap, Johnathan Goodwin, he just opened up his own company called Hline Conversions. We are mostly putting the duramax motors in H1's and 2's but we just did an 07 GMC Youkon that we swaped the body over to an 8 lug chassie with the duramax and we are currently putting a duramax into an 07 Caddilac Escalade EXT that is all blacked out sitting on air ride and 26" Dub Dirty Dog 2's for SEMA this year as well as a couple other customer vehicles.
Here are some pics of some of the vehicles:

The bosses bagged H1, runs on: Bio-Diesel, Bio-Diesel and Ethnol, Propane, or Hydrogen:

H2 Getting it's heart transplant:

H1 about to go back on it's frame with it's new Duramax:

Saw the same episode, that thing would fly! Ate the Ferrari for LUNCH!

72freak · 08-02-2007, 10:42 AM

Yep.............I swapped back to diesel the smart and quick way and it cost less than trying to do anything with a Duramax.

**Classic Heartbeat** · 08-02-2007, 11:21 AM

Yep, me too... I was loyal to the lable though.. Duramax Rock!! WES

BCOWANWHEELS · 08-02-2007, 12:34 PM

When they put it in a Suburban Im all over it............cant be loyal and buy whats not made!!!!!! I wont own another post 99 GM until then either.

**Classic Heartbeat** · 08-02-2007, 02:30 PM

I guess that sounded kind of bad. Didn't mean to step on your toes there 72freak. I wish that GM would put a Duramax into a Suburban too. However my crew cab has lots of room too. It also gets 20 plus miles per gallon pulling my 24' fully enclosed trailer full of parts. WES

theside00 · 08-02-2007, 01:49 PM

So I could just drop a 4bt or 6bt right in and bolt it up to the TH350 tran and be on my way without having to do a lot of mods? This has gotten me intersted now.

I know zippo about diesels, but I'd bet a dollar to a doughnut, a TH350 wouldn't last more than a few minutes under full throttle pulling behind a decent diesel, with say 600+ lbft of torque. And I'd be a little insecure with even a TH400 behind it.

I'd be interested to find out otherwise.

Robert1970C20rstbukt · 08-02-2007, 10:23 PM

I think it would be awesome to have a 6.2 in my pickup. I've heard that they're not good engines but hell the military used 'em in their CUCV trucks and blazers so they must be good!

theside00 · 08-02-2007, 10:35 PM

Is the 6.5 or 6.2 a direct bolt in as well?

I am not sure of the direct fit, but the 6.2 can be a good motor or the 6.5 . There are just slower than a herd of turtles. compared to the newer diesels. I have also had problems with overheating on these motors some say it is just a chararistic of them. Then again it could be I just had some bad luck with ones I have had.

this raises another issue I would like to have answered:

what is the legal situation of swapping in a diesel? I am in texas, if that matters.

You will only have issues if you live in an emmisions state that tests older vehicles. You can take a diesel vehicle and put a gas engine in it and not have to have emmisions testing...but you will have to have the vehicle re-certified as a diesel if you go from a gas vehicle to a diesel vehicle if it faklls under the years that they test.

Other than the emmisions issue...there are no other legal issues

skchevota · 08-02-2007, 11:50 PM

Got a 5.9 cummins in mine!

rwgregory · 08-03-2007, 03:15 AM

If Ford is a partial owner of Cummins, then why is it that all Ford diesel engines are manufactured by International Harvester???

OLDIRON69 · 08-03-2007, 08:22 AM

No emission laws in Texas on a diesel. I do know that. Plus we are exempt in our old trucks anyway, gas or diesel.

There are no emmisions testing on any diesels anywhere yet as far as I know but if you were to take a newer GAS engine vehicle that is in the system as a GAS engine truck and you put a diesel engine in it...you are still subject to the laws of a gas engine until you have the vehicle re-certified somehow.

Now most states dont test any vehicles that are over 25 or so years so it wont matter. I think California might test older ones
