This is one cool project

Re: '82 Duramax diesel conversion
 

Very cool looking truck...

Re: '82 Duramax diesel conversion
 

I cant tell you how bad I want to do this. Just a little too expensive for me.

Re: '82 Duramax diesel conversion
 

I've had buyers remorse a few times after the $6000+ initial motor/trans/transfercase investment.

Then I had to buy the $3000 Suncoast converter/transmission kit so it will handle the 500rwhp tune I have for it.

At least I only things I still have to buy are tires, wheel, interior, stereo, rearends & driveshaft....

Re: '82 Duramax diesel conversion
 

Nice project!

Re: '82 Duramax diesel conversion
 

watching this one

Re: '82 Duramax diesel conversion
 

I will be sure to keep watching this. I have wanted to see someone do this for a while. The trucks gonna be insane!

Re: '82 Duramax diesel conversion
 

Awsome project.Like the way it is headed.
Keep up the nice work.

Re: '82 Duramax diesel conversion
 

Any cab/Allison clearance issues?

Re: '82 Duramax diesel conversion
 

There is considerable interference with the floor.

I had to do a lot of engine/trans alignment as well as a small body lift to keep the body off the rear of the trans. I refuse to cut the body as I want to keep the original look... hoping it looks like a factory install when it is done.

Re: '82 Duramax diesel conversion
 

Wow
very cool build....
The finished product will be down-right MEAN :metal:

Re: '82 Duramax diesel conversion

Re: '82 Duramax diesel conversion
 

Did you have to drop the driveline down to clear? I have heard of several people start this and then stop because of fitment.

Re: '82 Duramax diesel conversion
 

Had to build a new crossmember for under the engine & modify trans crossmember. I also had to raise the body slightly.

Re: '82 Duramax diesel conversion
 

there is a few square bodies on thedieselplace.com that ham dmax swaps

Re: '82 Duramax diesel conversion
 

Great Idea. I am a big fan of the Duramax. Is that an LLY engine?

Re: '82 Duramax diesel conversion
 

Yes, it is an LLY.

Re: '82 Duramax diesel conversion
 

Any updates? I am seriously concidering this swap!! If you didnt raise the body, how much of the floor would have to be cut?

Re: '82 Duramax diesel conversion
 

It depends on how you mount the engine. With mine, I barely got by with lifting the body 1-1/4".

Re: '82 Duramax diesel conversion
 

Good job man cant what to see done:metal:

Re: '82 Duramax diesel conversion
 

Made a little progress this weekend.

Added some MegaMat to quiet the noise. It really hurt to cover my nice paint....

Got the firewall plate permanently installed.

Added a dash picture... although not finished yet. I still have to modify the radio opening & modify the opening for the column.

Re: '82 Duramax diesel conversion
 

That dash bezel is cool!!!
How did you make it?

Re: '82 Duramax diesel conversion
 

Great progress!

Re: '82 Duramax diesel conversion
 

Lookin good! I like the dash panel.

Re: '82 Duramax diesel conversion
 

yeah how did you make the dash fit? more pictures

Re: '82 Duramax diesel conversion
 

That dash is sweet. Well the whole project is :lol:

Re: '82 Duramax diesel conversion
 

nice project

Re: '82 Duramax diesel conversion
 

The dash has actually consumed more time than making the engine fit.

Will try to finish up the fitment of the heater box & parts this weekend.
I'll post more pictures then.

Re: '82 Duramax diesel conversion
 

This is gonna be a cool truck

Re: '82 Duramax diesel conversion
 

any updates?

Re: '82 Duramax diesel conversion
 

Progress has been slow with the holidays & work related distractions, so I have not touched it in about a month.

Started mounting the steering column, & trying to find an appropriate seat type/location for the truck.

I really want a set of newer leather heated seats, but I will not hack the floor to install them. The ones in my Yukon are much higher, but I would like to find something similar that fits. Thinking buckets with a console/center seat like some of the pickups had. There are a few aftermarket ones out there, but either really expensive, or a little cheap looking. Anyone have any recommendations?

Here are a few more pics.

Re: '82 Duramax diesel conversion
 

This is what I had to do to get my 01 Sierra seats to work.

Re: '82 Duramax diesel conversion
 

Yes, I previously saw your post with the newer seats & really liked them, but then saw you had to cut the floor. I will not cut anything on the truck as I am trying to retain an unmodified look. Your seats look like they are at a good height though. Not sure what to look for now....

Re: '82 Duramax diesel conversion
 

Any ideas?

Re: '82 Duramax diesel conversion
 

Made some progress today.

Got a steering column built. Added about 11" to the length & welded on some new brackets.

Re: '82 Duramax diesel conversion
 

I installed seats out of an 04 chevy pickup and i didnt have to hack up my floor but instead i cut off the tracks so i cant slide the seats back and forth but there isnt much room to do that anyways. after that you just have to make brackets to have the seats sit the height that you want. Trust me if you can make that dash and everything else fit in you can make the seats fit haha

Re: '82 Duramax diesel conversion
 

Do you have any pictures to see how they fit?

Re: '82 Duramax diesel conversion
 

I will as soon as i get home this weekend, i dont have any up here at school. to give you an idea the bottom of the headrest is right at the bottom of the back window. I am about 6' tall and it is right about perfect. basically once you get the tracks cut off you only need to make a couple brackets to accomadate for the floor.

Re: '82 Duramax diesel conversion
 

Where do you get the MegaMat?
I tried google but didn't find anything

Edit: I found it, It is a FatMat product, no?
