Yes I know it has a gmc grill po installed that from a collision repair. I kinda like it, gonna leave it. Currently the truck runs and drives so the mods will be over time, one at a time so the truck isn't down huge amounts of time.

I was born in 1971 and have been looking for a 71 burb for a while. Found a 71 pu initially but now found this burb I'm really excited about the build. I am an ase master certified GM tech. I am retired now and just play with my toys in my private machine shop.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

The build; I have a new crate engine LS3 hotcam Mtr 520hp, stage 4 4l80e trans, rebuilding a np205 with new timken bearings seals and gaskets. Rebuilding a dana 70 front axle with new spicer bearings seals gaskets king pins and u joints 4.10 Yukon gears and Detroit locker, rebuilding a 14 bolt full float rear with new timken bearings seals and gaskets 4.10 Yukon gears and Detroit locker rear disc brake conversion, New skyjacker 4" all spring lift kit, and new BFG 35" all terrains. I have a 73-87 burb safari full length roof rack that I will retrofit. Will build from scratch front and rear rock crusher bumpers with winches. Build full side rock crusher step bars too. I have a safari snorkel kit for a 73-87 burb I will retrofit as well.

Plan on putting late model burb seats in it that I already have too. Paint will be themed like a 71 cheyenne super pu, white roof, med blue, white stripe down side then med blue at bottom again.

It's going to be an interesting build. That's a nice parts truck. Do you plan to use it's longer springs? You might need a lift as the "K" - LS conversions I've seen leave little front axle-to- oil pan clearance. You might consider cross over steering as these 4x4's can have some bump steer.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

Not using the lift from the truck. Using hydraulic assist steering. The ls3 crate motor has a corvette low profile oil pan so clearance won't be an issue like on a ls truck pan.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

Forgot to mention using hydro boost setup from 1 ton, and 4 wheel disc brakes

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

Thanks for the info on the bump steer dave

Overall I like it

Can't wait to see the finish product those old suburbans are pretty sweet

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

Looks like a great project/starting point. Any idea what the seats that are in in now are out of? I'm interested in how the late model burb seats will fit too.

Is it me or is the roof raised up?

Paul

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

The seats appear to be '93 Suburban seats. i was going to ask about the roof also. I thought it just might be an illusion.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

It was a rural small town ambulance early in life and the roof has a small 3" rise. Not as bad as some ambulance roofs with like 12-14" roofs.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

Yes Dave is correct, currently has 1992-1994 suburban seats. I have a set out of a 2004 tho that are going to go in it.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

After doing some research it appears it was likely a rural fire rescue ambulance kinda thing on the roof

This is not my truck, but it is the truck inspiring my build. Attachment 1271964

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

Very cool build you have going here.


IIRC,there was an article about this yellow suburban.
One of the 4x4 mags maybe ?

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

i really like the yellow truck. I picked up my blue one today

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

the old window tint needs to come off, and the lift kit and tires and wheels need to go on. a good interior vacuum and very minor rust repairs. very very little rust. im surprised.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

the initial list will be; remove the tint, then install dana 70 front axle, front lift springs, front wheels/tires. then 14bff disc brake rear axle, rear lift springs, rear wheels/tires.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

It's so much easier to work on the front stuff, including LS cross member, when the front sheet metal is removed.

Re: 1971 K30 burb - LS3, 4l80e, np205, Dana 70f, 14bff, Detroit lckrs, 4"lift, 35" BF
 

I agree Dave. But at the moment she currently runs and drives so I'm not dropping in the ls just yet. I'm going to do axles, suspension, brakes, wheels and tires first. Then drive it a month or two before ls3 4l80 205 get dropped in it.
