Re: 1988 Suburban "V Rig" Gets Cummins Power
The truck has a 6" iirc.

Re: 1988 Suburban "V Rig" Gets Cummins Power
That's what I remember Ryan telling me was 6 inches.

Re: 1988 Suburban "V Rig" Gets Cummins Power
Great work and cool build. In case you havent found a steering box brace, the ones from off road design are the best. Ive used many and its really worth the $60 or $70 for it instead of fabbing one

Re: 1988 Suburban "V Rig" Gets Cummins Power
The steering box brace showed up last week, last Thursday I power washed the front axle and under the body. I tried to get every nook and cranny I could. I also did the frame more too. This week the fuel lines should be in as well as the new brake lines. I've been working on the engine getting it ready to go. 8 out of 12 exhaust manifold bolts broke off, all the internal bolts that secure the gear housing to the block were loose, and there was no tab on the KDP. Also the crankshaft had bad pitting on the sealing surface for the rear main seal. I had to install a sleeve and different seal on it. Now the pan and front cover are back on. Tomorrow I'm going to install a new tappet cover gasket, clean the engine again, and paint it. Oh yeah, I already advanced the timing on the injection pump, and the engine is getting a little bigger injector. Getting closer...........

You have been busy, sure sounds like that motor needed some work.

Re: 1988 Suburban "V Rig" Gets Cummins Power
It's a 12V head atleast, the 24V's are more fun for drill bolts out of.

Re: 1988 Suburban "V Rig" Gets Cummins Power
I've never seen the difference between the 12 and 24 valve heads besides thr valves themselves.

Re: 1988 Suburban "V Rig" Gets Cummins Power
24V is smooth with the head:
http://i191.photobucket.com/albums/z...DSC00214-1.jpg 12V have "ears" that stick up above the runner and are easier to drill and tap than a 24V http://i181.photobucket.com/albums/x...r/000_0014.jpg |
Re: 1988 Suburban "V Rig" Gets Cummins Power
That does look like a pain. Have fun with that Ryan!

Re: 1988 Suburban "V Rig" Gets Cummins Power
I've been working away on this thing. I have the front cross member done, welded in the steering box support plates, got the engine painted, and the injection pump now has a 3k gov spring in it. Now the engine is getting new injectors, and a Denny T stage II fuel pin. This thing should run pretty good. I'll try to get more pics later. Hopefully before the weekend I can have the engine sitting back in the frame.

Re: 1988 Suburban "V Rig" Gets Cummins Power
Time for updates! I've been sweating my butt off working away on this thing! I got the front cross member and engine cross member finished and bolted back in. I also installed some heat/sound deadener insulation on the fire wall.
http://i181.photobucket.com/albums/x...IMG_0005-1.jpg http://i181.photobucket.com/albums/x...IMG_0006-1.jpg http://i181.photobucket.com/albums/x...IMG_0010-2.jpg Got the engine painted and the injection pump installed. Also installed the SFI rated flex plate. http://i181.photobucket.com/albums/x...IMG_0008-2.jpg http://i181.photobucket.com/albums/x...IMG_0009-1.jpg Yesterday I sat the engine back in it and hung the transfer case on it to see what mods are next. I'm going to have to cut the cross member and clearance it for the drive shaft. The drive shaft also needs lengthened. I installed the starter, hooked up the fuel feed line, installed the OE oil pressure sensor, and have to get a bushing for the OE water temp sender. http://i181.photobucket.com/albums/x...IMG_0025-1.jpg http://i181.photobucket.com/albums/x...IMG_0019-2.jpg http://i181.photobucket.com/albums/x...IMG_0021-2.jpg http://i181.photobucket.com/albums/x...IMG_0022-1.jpg http://i181.photobucket.com/albums/x...IMG_0026-1.jpg |

Re: 1988 Suburban "V Rig" Gets Cummins Power
I finally got the D70 in the rear of this and got the turbo and exhaust manifold back on. I have the down pipe built, now to finish the exhaust and build the trans mount. Been cleaning parts and pieces and painting them, installed the new water pump, and removed the dodge truck harness and PCM. I'm going to use it to run the alt, grid heaters, and over drive on the trans.

Re: 1988 Suburban "V Rig" Gets Cummins Power
Been plugging away at this thing. Anyone that says these don't take much time, must not know. :lol: The exhaust tip is just tacked on there to see if I like the angle the pipe is coming out at. It does have 4" going over the tcase too.

Re: 1988 Suburban "V Rig" Gets Cummins Power
I've got to figure out where the trans cooler is going to go now, and get the trans linkage figured out. Still waiting on the radiator and drive shafts, then I need to finish up the wiring. Yee haw!

Re: 1988 Suburban "V Rig" Gets Cummins Power
Cool build! Where did you find the GMC grille without the emblem base molded into it?

Today I spent 4 hours installing this. Wow, I'm glad I don't have to do anymore of these for a while. :lol:

Re: 1988 Suburban "V Rig" Gets Cummins Power
Here is some more progress pics. The radiator support is done, I just have to paint it. Been working on replacing the tie rod ends, installing the DIY4X spring plates on the D60, got the fan hub and belt on the engine. Fuel lines are installed and hooked up, and new injectors are installed.

Re: 1988 Suburban "V Rig" Gets Cummins Power
More done. Inner fender repainted.
http://i181.photobucket.com/albums/x...031_125300.jpg New pulley for A/C set up. http://i181.photobucket.com/albums/x...031_125017.jpg A/C bracket. http://i181.photobucket.com/albums/x...031_125028.jpg Throttle cable set up installed, transmission pressure cable brackets hooked up and I got the cable adjusted properly. http://i181.photobucket.com/albums/x...031_125037.jpg Here was the first shot at making the trans mount. I ended up removing 1 1/2" of height from it to get the transfer case to clear the floor board. This utilizes the stock NP205 tcase rubbers. This truck had poly ones, so it worked out really well. http://i181.photobucket.com/albums/x...025_121410.jpg http://i181.photobucket.com/albums/x...025_121420.jpg http://i181.photobucket.com/albums/x...025_121428.jpg I have to remove the trans cross member and add gussets to the area where I raised it to clear the drive shaft. Tomorrow I will finish the front axle shock mounts. We had to put the mounting bolts in the mini lathe and turn them down from 3/4" to 1/2" so the chevy shocks can be used. |
Re: 1988 Suburban "V Rig" Gets Cummins Power
When I was repairing the LH fender, I realized the radiator support had another broken piece. It was still bolted on the fender. :lol: I fixed it and then repainted the entire support.

Re: 1988 Suburban "V Rig" Gets Cummins Power
Did you make the AC bracket? I want one!
Is the frame stock or reinforced? Great work by the way, I can't wait to get started on mine. Keith |
Re: 1988 Suburban "V Rig" Gets Cummins Power

Re: 1988 Suburban "V Rig" Gets Cummins Power
We've been working on this beast making progress. Here's a shot of one of the inner fender mounting tabs broken off I repaired.
http://i181.photobucket.com/albums/x...101_114320.jpg http://i181.photobucket.com/albums/x...101_115059.jpg Here are the front axle shock mounts completed and shocks installed. http://i181.photobucket.com/albums/x...101_115111.jpg http://i181.photobucket.com/albums/x...101_115203.jpg Here are the sway bar mounts incorporated with the leaf spring retaining plates. http://i181.photobucket.com/albums/x...101_115211.jpg http://i181.photobucket.com/albums/x...101_115150.jpg I had to take the rear drive shaft back again. When they built it, they didn't take into consideration the slip joint moving because it was almost bottomed out. They had to take out some to get proper travel. The front fits really nice. Too bad I broke a tap off in the rear pinion yoke. Someone had the hole cross threaded and I was trying to save it. I'm working on getting a different yoke now. http://i181.photobucket.com/albums/x...113_120125.jpg http://i181.photobucket.com/albums/x...113_120112.jpg http://i181.photobucket.com/albums/x...113_120104.jpg I had to cut a hole in the floor pan to get the 4wd shifter from the dodge to fit in here. I also had to modify the shifter mount to allow being bolted to a 47rh, since they never were designed to be there. I didn't to weld steel back in there because I didn't want the windshield and interior burnt by welding. So I made a cover out of aluminum, riveted and sealed it in. I will show pics of the modified shifter bracket later. I did get the shifter to come through the stock hole in the floor as well. http://i181.photobucket.com/albums/x...108_104009.jpg http://i181.photobucket.com/albums/x...108_103957.jpg http://i181.photobucket.com/albums/x...113_100540.jpg http://i181.photobucket.com/albums/x...113_120018.jpg http://i181.photobucket.com/albums/x...115_121216.jpg |
Re: 1989 Suburban "V Rig" Gets Cummins Power
I got a new A/C compressor and mounted it so I can get a belt for it. i also ran into another issue. I had planned on running the stock upper intake from the 93 Dodge truck. Wrong. The stock dodge elbow points straight into the chevy master cylinder and you can't get the charge pipe in there. So, I had to use a 2nd gen 12v intake horn. And again, another problem. They were designed for P-pump configurations, not VE rotary pump engines. The 2nd gen style has an ear coming off the intake bolting farther forward to help support the intake and on some providing a mounting point for the dip stick. I had to cut this part off to be able to bolt the intake on due to an injection line being rightin the way of this extra ear. No big deal. This intake will be getting polished as well before it's all done.
http://i181.photobucket.com/albums/x...113_120154.jpg http://i181.photobucket.com/albums/x...106_144554.jpg http://i181.photobucket.com/albums/x...106_144840.jpg http://i181.photobucket.com/albums/x...106_153114.jpg I also ran into another snafoo. Since we used the dodge steering box, the drag link is hairy. Can't use a chevy one due to them being too long. Can't find any DOM threaded or anyone to thread it for what I need to do. So I came up with this. I have to weld a gusset on each end still. The owner is going to run this until he switches over to cross over steering later. http://i181.photobucket.com/albums/x...102_114249.jpg http://i181.photobucket.com/albums/x...102_114258.jpg |
Re: 1988 Suburban "V Rig" Gets Cummins Power
I'll take more pics this weekend. We got the LH hub bearings re packed and inspected, and all put together. Started putting exhaust hangers on the exhaust, trying to knock out things little by little. We got the radiator support bolted back on and have both fenders realigned and ready to go. Let me tell you, that was a PITA! :lol:
|
Re: 1988 Suburban "V Rig" Gets Cummins Power
Looking good man. That drag link looks a little scary. It looks if the drivers side drops down any that the joint on the steering box end is going to come to the end of its stroke. Or maybe even turning to full lock to the passenger side.
