Re: 71' suburban 4x4
 

Got a hold of some seat pedestals from M&M U pull it on Friday. Got an awesome deal and they also have slides so I will not have adjustability forward and back :metal:

Tested my Cobra 29 LX BT on Saturday and the NOAA channels are very nice.

I should be CNC'ing the grill Tuesday, I get one chance so hopefully it works out. Not sure if I touched on this but it will be similar to the General Mayhem but with a nice Stainless surprise.

I am considering putting cab handles on... Thoughts on these?

I am also adding Cab marker lights as this will give me a place to run RF/Power to the roof rack.

Re: 71' suburban 4x4
 

Another thing I forgot to mention is stainless cable steps for getting into the cab so when they hit rocks they just swing out of the way. I am also planning aome sort of handle to help pull yourself in. Thinking of a rope handle or something that attaches to the drip rail.

Re: 71' suburban 4x4
 

Okay guys I am having a debockle with adding A/C. I picked up a factory dash setup, but my research shows that running the factory Evap core on R134a even with a modern condenser will mean I will have luke cool air.

Anyone know of an R134a Evap core that fits the factory heater box?

Re: 71' suburban 4x4
 

I thought it was the POA or the orifice tube that really controls that? The evap cores are all very similar, the liquid coolant goes in and boils off, there isn't a lot that can be different, but I may be wrong

Re: 71' suburban 4x4
 

You need to recalibrate the POA valve and run a true parallel flow condenser. If running the stock or piccalo (sp?) style in a hot climate you need to run an electric fan to keep the air cool when airflow over the condenser is minimal (slow speeds, traffic).

Re: 71' suburban 4x4
 

I have to eliminate the lever type cable control for the air/vents on my 1971 K10 Suburban project to make room for electronics. My goal is for the new setup to not protrude off the inside of the dash more than an inch.

Choke cables are cheap off Amazon so that seems like a good place to start. I am also adding A/C and a re-circulation control as stock did not have one. I should be able to better control the temperature.

Of course I can't simply just make a plate to mount the cables and fan switches, so I am 3D printing it such that text describing each control will be back-lit. Now instead of having text just lit up that tells you to push the cable for this and pull for that, I am 'simply' going to illuminate for example the 'hot' text when the temp door is on heat, and illuminate the 'cool' text when it is on A/C, however these are not on/off settings, they are linear. So my plan is to hook Linear Pot's to the cables and have the illumination fade with the control of the cable.

Here is the current drawing: http://i.imgur.com/THKa9Dy.png
I am going to play with the slot as I am also adding Rear A/C and want a separate fan control.

Re: 71' suburban 4x4
 

I have found a modern A/C evaporator core than based on the dimensions will fit in the factory heater box, I will update with more info and do an A/C thread when I have confirmation. My goal is to just run one evap core with all R134a parts and a well sealed cab/re-circulation setup and not need a second core.

Progress is slow as this is finals week. Not sure if I mentioned this but my buddy that was over helping Fab'd up a custom intake plenum to use a 6bt heater grid so that is ready to go on sans gasket(s).

The one chance to cut the rest of the grille was a failure as somehow the file was an inch taller. So I am hopefully cutting the final piece tomorrow. Steel is not cheap when you don't buy a full piece :(

Re: 71' suburban 4x4
 

Well the trans in my F350 went after being rebuilt a month before so I through my Burb together in a week and test drove it 350 miles to school, made it with few issues!

http://i.imgur.com/AxtSwS3.jpg
I averaged 18mpg. I believe I get around 30mpg at roughly 60mph and 20mpg at roughly 72mph with rolling hills. I need to work on sound deadening, thinking of using Yoga mats because I can not afford Dynapad and/or Dynamat.

Re: 71' suburban 4x4
 

Nice build and sweet burb! Did you use toggle switches or a controller on the 47rh?

Re: 71' suburban 4x4
 

Because it got thrown together, it was quite Roadkill. Especially with the OD control. I was confused in nomenclature and only have a 46rh. I ran the OD solenoid off of key'd hot. Because my FSS was inoperative I could turn the OD off by turning the key off and keep driving, but then also lose power brakes because the day before I was scheduled to leave for school I found my vacuum pump was not creating vacuum so I grabbed an electric one from S&K Speed.

I plan to put it on a foot switch as that is how the OD is controlled in my F350 so it is basically instinctual for me.

Re: 71' suburban 4x4
 

How did you mate the 46rh to the 4bt?

Re: 71' suburban 4x4
 

My 46rh came out of a 93 W250 with a 5.9 Cummins so it had the adapter plate, TC, and flexplate/flywheel that I needed.

Re: 71' suburban 4x4
 

Does your valve body have a 3 pin or 2 pin connector? If it has 2 it is a a518. If it has 3 it is a 47rh. 46rh's were behind gas engines and have a smaller bell housing.

Re: 71' suburban 4x4
 

I have no idea what is because as from the begining, everyone has a different story. It does not have lockup but has OD and came from a 5.9 Cummins. I was told 47rh has lockup and 46rh does not ans is more stout.

Re: 71' suburban 4x4
 

If you have overdrive and no lock up, you have a 518 which is an updated 727 with over drive. 47rh's were only put in v10 and cummins 2500 and 3500 1994 and 1995 trucks. I've seen a 47rh In a super late 93 first gen, but it could have been swapped in at some point. The 46rh's are gas transmissions and do have lock up and overdrive like the 47rh. They never had the bigger bell housing. They were behind 360s and maybe 318s. I can show you pics as I have everything besides a 727, 48, and 68rfe.

Sorry for hijacking your thread. Have any underhood pics of the beast?

Re: 71' suburban 4x4
 

Nice work. Thats a heckuva test drive!

Re: 71' suburban 4x4
 

Supposedly this came from a 93 W250. It came with an NP205. I did have an issue with the TC fitting but my engine had a pilot bushing.

Special thanks to Hawgee.com for the [BROKAGAIN] vinyl. If anyone has trouble seeing at night you've got to get these Cibie Z-beam fixtures and 90w low beam H4's.

Do you have a link?

Link for what?

Does anyone know the difference between the inside door handle mechanism from 67-71 and 72?

Re: 71' suburban 4x4

Sounds like a good time.

The shafts on the '72 remote door handles and window regulators are longer because the door panels are thicker.

Re: 71' suburban 4x4
 

But the Metal of the door is the same? I have 72' Front doors from Cali to go on, but want to use my 71' guts and am doing custom inner panels.

Re: 71' suburban 4x4
 

Dynamat is not sound deadening, it is vibration dampening. Mass loaded vinyl is sound deadening. You only need about 50% coverage with vibration, sound you need 100% coverage, or as close as possible

Re: 71' suburban 4x4
 

I guess Dynamat's Dyanliner is their sound deadener. They do sell sound deadener. I am more interested in thermal insulation which I guess I would also need as close to 100% coverage as possible?

Either way do you know good cheap materials?

Re: 71' suburban 4x4
 

Unfortunately, there isn't really a cheap way to do sound deadening. It's all really quite expensive, I am in around $1,000 in my Suburban, and I am not even done yet. You can buy that peel and seal from the hardware stores pretty inexpensive and get the vib dampening at least

Re: 71' suburban 4x4
 

a friend of mine recommended hvac duct insulation, not sure if thats the peel and seal you are referring to but he says it works great and is fairly inexpensive.

Re: 71' suburban 4x4
 

I think the 67-71 pieces will bolt on a 72 door. The wing windows have an extra bracket on the 72 models and there is an extra hole in the door shell to mount this extra bracket on the wing assy.

Re: 71' suburban 4x4
 

I am looking at modifying my Cobra 29 LX BT to have a remote mount face plate and then using a factory style dual speaker for the CB. Then use the other cone from the dual speaker for the HAM radio, but I don't know if these will need to be amplified. Anyone have experience with this? I will be making custom speaker enclosures for my actual speakers so this would be unused otherwise.

Got some shelving built for the tools and camping gear, model airplanes loaded up for the trip to South Carolina. http://i.imgur.com/l4GaAVv.jpg
Got the second fuel tank mounted which needed a small amount of modifications to work with the trailer hitch and I had to modify the filler neck to deal with the cross member, pictures to come of this.

Using a fuel valve out of an 86' Square body because I had it. This year valve uses a motor instead of a solenoid and retains its position until you tell it to switch.

Re: 71' suburban 4x4
 

just curious, saw your post in the 4x4 trucks page and you said 32mpg, what speed were you going, what gears you got, and what tire size. I don't know much about the differant 5.9's but is yours computer controlled or mechanical

Thanks!

Re: 71' suburban 4x4
 

If I said 32 it was a typo, meant 30. 30mpg is achieved at about 60mph with 3.73 gears, 235/85/16 tires on about 45psi of air. Running a Dodge A518 OD trans with an NP205 behind an 1985 fully mechanical 3.9(4BT).

Re: 71' suburban 4x4
 

just realized it was a 4 cylinder, pretty slick
