1990 GMC Suburban ... Cummins Powered

[thirdstreettito]

Separate the silver and black with a white pinstripe. It'll set it off!

I have a few questions:
Are you leaving the Cummins stock or doing power/reliability upgrades?
What is the minimum lift required for a Cummins?
Would 4.10 gearing be a Bad Idea?
Are there any cockpit clearance issues (radio area, drink holders) with the NV4500 HD?

I apologize if you answered these previously; multiple searches on this site are a bear due to re-search time requirements. I've converted my own '91 6.2 turbodiesel burb to a 2500 (hence the 4.10) but the 33" KM2s rub a little on turning. 20 year old suspension is crap anyways. When I replace springs though, I want it be lifted just enough to accommodate your drivetrain choice, because when the 6.2 goes it's Cummins Time.

Oh and your Suburbeast is coming along nicely!

For my build stock right now is just fine , I could see possibly fuel plate in the future but for a truck rolling on two different sizes 42 and 44"s with the 4.56 is just fine .
You can put a cummins in a stock truck just is a tight squeeze .
I have a 1" aluminum body for my clearance ... my suspension is custom Deaver springs and gives me a good 10" lift .
4:10 is a good ratio depends on your tire size and trans .
My NV4500 shifter is in the same location a stock shifter would come threw the floor on a factory truck .
All I can say is look thru my build and it was a ton of work ... I have basiclly worked on the truck just about every day for the past year and a half ... should be done for spring .

Greg,
thanks for the info on the clearances. I forgot all the trucks that came with manuals would have the same cockpit; good to hear it works fine. I know the Cummins likes to run lower than the 6.2 but you're right I could just keep putting on larger tires

Yeah the work you've put into this thing is next level. Yours will be a factory-new rig that never was but should have been.

Nice work!

Found some time to work on the rig ... got the body side bars on , painted the hood black and not sure how happy I am with that ... its on .
I just finished fabing up the grill . It was a GMC grill that I skinned the inside out and found some aluminum mesh ... think it looks like a ford raptor grill ...LOL
My buddy put the windshield in last week , I was able to track down a factory NOS gasket ... it was a pain in the butt .
I did side quarter windows and they were pretty tough plus I used sealant between the gasket and body to make sure no water gets in there .
Headline and some of the inside panels are all back in .
I put the 42's on the front when I was building my side steps ...
Just picking at it .... enjoy the snow .

Despite the fact that the hood would look more appropriate silver, the truck still looks bad ass! Looks like a classy zombie killer!

[flomulgator]

That thing looks like a beast now!

Beautiful!

I don't know if I like the hood black either. But, the sub looks sweet for sure. Nice work on the grill and steps. If you painted the roof black, that hood would look so sweet black!

[thirdstreettito]

I just wish the bumper was moved up about 2" so there isn't a huge gap. Other than that its kinda sweet.

[greguw]

I'm not sure on the black but paint is easy to change ... the gap will be addressed , I am not finished with the front bumper , along with fixing the gap I am making a hard cover to go over the top of the winch .

Nice!!!!!!!!!!!!!!!!!!!

I only have one thing to say about this build.... AWESOME!!!!!!

I'm getting way too many ideas and wild dreams about Burb builds than I could ever hope to afford.. Jealousy, I have found it.

This Por-15 paint that you sprayed on the frame, is that an oil-based paint? Do you need to add hardener to it? Can you use it on rusted spots? How did you grind/brush on top of the frame underneath the body?

[greguw]

Por works better with rust , I ground and sand blasted most of my frame . I applied my Por 15 with a spray gun .
I still have to paint the axles and other chassis parts and going to brush and spray ... stuff works great .

[greguw]

Had some time to weld in some fillers and paint the bumper , looks pretty good , I made up a aluminum cover that will go over the winch to keep it out of the direct weather .
Started to put turn signals in ... they look great but the one on the passengers side did not lock the light socket in and waiting to hear back from Classic parts to see what they want to do .
I have to make a custom secondary hood latch because the intercooler is right where the barb goes into the core support ... its allways something .
Just keep making forward progress , I am hoping to have this done by spring .

[thirdstreettito]

Why not just mount the bumper higher and do it the proper way? Rather than put a piece of metal in like people do with 3" body lifts. I dont understand...

[greguw]

If you look threw my build , truck has a 1 inch aluminum spacer on top of the poly body mounts . I fabricated the winch mount and had a bumper of a newer dodge . it was the only shell that would fit around my mount . plus I still cut the center out of the bumper .
The gap was not due to the a body lift just when you get into fabricating its not a exact .

[greguw]

Found some time to pick at the truck ... All the door glass and most of the seals are in , waiting for the front door bead seals , did all new motors , the regulators were in great shape .
Not the truck is just nickel and dining me to death ... rear air bags , rear track bar and brackets , front ORF joints for my crossover steering , steering wheel and adapter .
I'm adding the Firestone Air bags to control and body roll and also a rear track bar just incase I do any towing to keep the axle from pulling around .
I'm down to putting the dash and door panels on the inside , then front end alignment , vent hoses and tubes . Then some chassis paint .... should be done by may .

[YoungBurb88]

This has been one lengthy build, but when you're doing it to the quality levels that you are... I think the time will be WELLLLLLLLL worth the waiting.

[Dieselwrencher]

Hey, at least you're getting down to the nitty gritty! It'll be drive time soon! Great work, keep at it!

[68Timber]

Nice to see it in the home stretch, just awesome. I like the black hood but if it hasn't quite grown on you, have you considered leaving the cowl induction hump black and painting the sides silver? A small black pinstripe next to the black cowl would blend it in well. Just a thought, I like it fine like it is. Keep up the great work.

Oh yeah, when I see updates now I catch myself looking for shop-cat.

[greguw]

Down the shop picking away this morning , I see a lot of builds that don't get finished , shame but **** happens .
The girl friend is driving down so I will get back on it Monday , still have a the little pile of parts coming in thats holding me up but the stuff should be in next week .

[manimal]

Damn that thing is AWESOME!!! ZOMBIE APOCALYPSE HERE YOU COME!
