Ken, at Autoworld conversions, has done a conversion similar to yours and it looked to me like it came from the factory with the 6BT. |

Well, a call to Ken and Jeremy and I had the answers I needed to solve my firm steering issue. The steering pump had air in the lines and by jacking up the front differential and turning the wheel left and right without the engine running removed the air pockets. Afterwards, I fabricated a stainless steel bracket to mount the coolant reservoir to the fan shroud. I then took it out for its first shake down run. I will describe it as "Awesome." I know it wasn't pulling a trailer or anything but it ran great and as for the 4L80E, it shifted so smooth that I was worried it wasn't shifting but the engine wasn't revved up. It seemed like an ATV with a CVT transmission.
Here are some pictures of the coolant reservoir, hole for the transfer case shifter and the Lokar transmission dipstick that I needed due to its flexibility. |

Re: 89 GMC Cummins conversion
Glad to hear it is under its own power now . A sweet truck for sure . The 24 V engine uses a ecm to run the eng correct ? What was the harness like to adapt to the chevy ?
I remember when I put the 92 eng in my 56 . The hook up and pluming was almost too easy . The 2 Ryan's help a lot . Other wise it would have just been easy . They get credit for the "too." Lol. |
Re: 89 GMC Cummins conversion
Those Lokar dipsticks have sure went up. I'm going to wait to see how a manipulated stock one fits my truck before biting the bullet and buying one. I hate filling the trans in my Vette that has one. Such a small dang fill hole.
6bt56, yes sir. The 24v ISB's use an ECM to run the engine. Mainly to control the injection pump etc. You basically use 7 or 8 wires from the dodge harness plus some for the OBDII connector and you can get them to run. It is a lot of wires to get rid of for sure. You pick out which wires go to the OEM cluster and use the stock GM fittings and adapt thread sizes if needed to get the stock gauges to work. Definitely not as simple as a 12v. :lol: |

So here what has happened in the last week: installed new exterior mirrors, painted and installed the grill and headlight doors, mounted front bumper, installed and hooked up new fuel lines down the left frame rail, installed hood, and got lucky and found a red GMC tailgate that was in really good shape.:metal: I also attached a picture of the bump stop extension. Sorry about the dirty vehicle but I haven't cleaned it up yet.

Over the last couple of days I extended the rear load level braking assembly. This had to be extended after installing the lift kit. I found a winter grille cover behind the rear seat. This will come in handy living in MT. I am still working on cleaning up and securing all the wires. Lastly, I didn't like the way the coolant overflow hose looked so I drilled a hole in the top of the tank and ran the line through the new opening. In hindsight I should have just left the factory overflow tank mount on the fan shroud.

Here is the latest: welded in the piece of metal that I had previously cut to move the transfer case lever over, scored me another GMC tailgate in really good shape, mounted and hooked up the transmission temperature gauge, and wire loomed the wiring under the hood. Getting closer to having it on the road. I still need my tire and wheels as well as having the exhaust finished.

I didn't mention it previously but I was worried about fan to radiator clearance and so I used the 1st generation fan clutch and fan hub. The fan itself is out of the 24valve and I raised the shroud just a bit and of course had to shift it over about 1". It seems to work but only time will tell. |
Re: 89 GMC Cummins conversion
Nicely done . It truely looks like it came that way. I can only imagine what would have happined if GM had made a deal with cummins in the good old days , instead of dodge
Looing forward to seeing it with new sneakers . |

I think its the red rockercover , it just makes everything else blend into the red firewall.
Got any pics of the other converted truck ? Keep up the good work |

This is the only one that I have available right now. I was going to take a picture of my 88 next to my 89 and then again after the new sneakers get put on it.

Re: 89 GMC Cummins conversion
Thats a good looken bed on that truck . All the cool square trucks rotted to death around here long ago. I go for a trip to the sunny south and Im amaised . Im having conversations in the 7/11 parking lot with guys with 20 year old trucks and complementing them . They look at me like im from the moon . Lol, Just a truck to them .
You said that truck has a 1st gen 5.9 and getrag? Thats the same combo I put in my 56 . Sure was straight froward . |
