89 GMC Cummins conversion - Page 9 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

72MARIO · 01-17-2015, 08:12 PM

Any updates i am curious how everything is holding up ? How about the mpg any better ?

COS399 · 01-18-2015, 02:04 PM

72MARIO - Thanks for asking but I haven't had any time to work on it. It will more than likely be a few months before I will get around to it.

I just got done watching the first episode of POWERNATION: Truck Tech involving the installation of a LBZ Duramax and Allison combo in a 1987 C10 short bed.

COS399 · 01-26-2015, 02:06 AM

I know it's not a Chevy and it's not like I have a lot of spare time, but the price was right! That is probably how most of our projects get started. I may one day put it in the "Alternate Tinkering" section.

**Dieselwrencher** · 01-26-2015, 11:49 AM

That is in really nice shape. What are the plans for it?

84chevyguyid · 01-26-2015, 01:41 PM

I dont recognize the brand, what is it?

Don't really have any plans at the time. I like it the way it is right now.

It is an International.

My brother saw the picture and immediately thought of a 6bt conversion.

84chevyguyid · 01-26-2015, 09:43 PM

That would have been my guess, what year? Does it still run?

COS399 · 01-26-2015, 10:17 PM

I think it is a '36 and not sure when it was run last. It would need some work to get it there.

COS399 · 01-26-2015, 10:19 PM

Here is a cool ad photo from back in the day.

**Dieselwrencher** · 01-27-2015, 08:04 PM

It would be really cool to slam that body on a newer school bus or FL70 chassis.

84chevyguyid · 01-27-2015, 09:06 PM

Hey that tractor trailer combo would be cool to haul the wheelers in, get that put together and bring it this summer to the dunes!!

Yeah, I will get right on that.

Yep, that could be an option. I need to drag it home one of these days and measure it up in case I go in that direction. It has a wooden floorboard and a two speed rear axle.

84chevyguyid · 01-28-2015, 11:39 PM

Got a new wheeler to load in it...

**Dieselwrencher** · 01-29-2015, 01:46 AM

Even his own big ol antenna!

Nice!

When my kid was that age you couldn't get him off his 3 wheeler toy. We had a dirt pile in the back yard and he would push that thing to the top of the hill and then ride it down. I got my kid his first ATV at the age of 2 1/2 years old and he raced it at 4 yoa.

Time flys by.

84chevyguyid · 03-02-2015, 01:02 AM

He really likes riding it, his legs are too short to pedal it yet so he just walks it around so far. Just got back from a fun bike trip to Mesquite Nv with my nephew and some friends. They like to go down there a couple times every winter, first time for me. James, you and Cody will have to go down with us next winter. The view out of our room was great! The weather even cooperated, was mid 60's every day. Rode around on some cool "Martian landscape" looking stuff for 3 days.

**Dieselwrencher** · 03-02-2015, 08:57 PM

That looks like it was a pretty cool trip!

COS399 · 03-19-2015, 11:05 PM

Mike- that looked like it was fun. We are getting closer to giving you dates for our St. Anthony's dune trip. I have to work around football and basketball camps that my kid wants to go to. I will PM you with the dates as soon as we can firm them up.

Until you see the price for insurance that allows it to haul a trailer. I have a Mack that looks a lot like that old international.

COS399 · 04-27-2015, 07:37 PM

No progress to report on this project. I did however buy '06 GMC with a Duramax/Allison combo and I have to tell you that I am impressed with it. Time will tell but one day I may be doing a Dmax/Allison swap into something.???

MTCK · 04-27-2015, 09:09 PM

Cool. Any D-max pics?

COS399 · 04-27-2015, 11:06 PM

Here are a few pics.

COS399 · 04-27-2015, 11:14 PM

I will get you a few more tomorrow that don't require a magnifying glass or cheaters.

**Dieselwrencher** · 04-28-2015, 12:24 AM

Very nice new ride!

COS399 · 04-28-2015, 07:19 PM

Thanks Ryan.

Here are some better pictures. It is a SLT model with all the bells and whistles and runs like it has been modified a little.
