Re: 87 V20 D/D and Road trip Burb
So the weather has been starting to change, and after my last backcountry road outing. It's time to get a matching set of gears in my Burb. I have been putting this off for too long. I think it has been a yr now since I swapped the blown out semi float for a 14bff. In the process I put the wrong ratio in.
So I need 3.73 gears. I have 4.10 in it now. With the 285/75/16 tires and the th400, the motor is running a tad high in the rpm band on roadtrips. I don't want to swap a 700r4 in, or go to a taller tire. After looking into the cost of a re-gear. I decided not to re-gear. I have been looking for a complete used unit just to drop in. I had lined up a proper donor from a 86 C20 Burb(gray) that was a factory 454/th400 truck. It even had the proper length e-brake cables and connections. That was two yrs ago(yes I had a 14bff swap planned). Then I sold it a yr later. Sob! |

Re: 87 V20 D/D and Road trip Burb
Fast forward. Came across this gem. I need to crawl under it and confirm, but for less than the cost of the re-gear. I could bring this home. It has more than just a 3.73 14bff.
I need to find out why he wants to sell... But if it is a runner, I might just have to swap my 4.10 unit into it and drive it. Or turn it into a donor. |

Re: 87 V20 D/D and Road trip Burb
A few of my fave codes.
GT4 with G80 L19 MT1 ZW9 because I have only ever owned tailgate burbs. This thing is pretty heavily optioned. The wood grain trim package matches my wife's 91. The blue seats in my 87 are pretty worn. My 70/68/78 Burb project needs a motor, f.i. BBC would be nice. Last edited by Jsfucttruck; 12-10-2017 at 05:21 AM. |

Well, things sometimes to wrong. In my case, more than less.
My diesel has been slowly running worse and worse. I replaced the lift pump and that helped a little. I was not seeing any bubbles in the return. It would miss in mid range rpm, it was hard to start warm, and randomly roal coal. I sent out the injectors and injection pump. 2 injectors failed the test and the pump looks to have water damage inside. How is that possible with only 42k on new parts? I run a racor setup with water seperator. I changed fuel filters with every other oil change. I rarely had water in the collection bowl. I wonder if my racor setup is not the best? At around $1100. I am going to reevaluate my situation. I am getting tired of the constant battle with this motor. Parts are a pita to source. Big D is going to get parked for a bit while I decide what to do. I am over spending $300-1000 every time something goes wrong. Any suggestions on how to keep mice/rats out of the engine bay and heater ducting. |

Re: 87 V20 D/D and Road trip Burb
Put drops of vanilla on the carpet. Maybe moth balls near the blower motor. Drier sheets have worked for me in the past but I've heard others say they had no luck with them. Sorry to hear about the 6.2 issues. Nothing diesel related is cheap these days.

Re: 87 V20 D/D and Road trip Burb
Good news.
I found a good used injection pump and 4 injectors off a j code motor for $200! Score! I am going to try to get it back together in the next few days. I also scored another 3.73 g80 14bff! I found a guy that wanted a 4.10 unit. He suggested we trade. It looks fresh inside too. Now I am itchy to go off road again. |

Re: 87 V20 D/D and Road trip Burb
Wow. So much for a few days...
Well the used injection pump and injectors did the trick! I ended up putting in a airtex E8053(?) lift pump and fuel pressure gauge. I had intended to put the pump down on the frame, but ended up on the pass side inner well. While I was looking up fittings for the fuel pump and guage, I came across a filter that would spin onto the 3/8" inverted flare inlet of the pump, with a 3/8" hose barb end. The whole combo is around 12" long. I drove it down to Coalinga and back, roughly 300 miles. No problems. While it was down, I traded a guy my open diff with 4.10 gears. He had a good looking G80 3.73 unit. He let me take his first and i was able to swap my backing plates, pinion guard and diff cover. The G80 engages nice with the low hp n/a 6.2. Let's hope it holds together. |

Re: 87 V20 D/D and Road trip Burb
Good to hear you got her going again. I agree with you on the G80, it should last a long time and work well with the 6.2.

Re: 87 V20 D/D and Road trip Burb
That's good to hear the IP and injectors took care of it. That diff cover still looks sweet too.

Re: 87 V20 D/D and Road trip Burb
I am happy to have it back too and it didn't cost me a arm and a leg to fix it.
I got a call from a bud that buys storage lockers and such called me and said he thinks he has a 700r4 with adapter and 205. With his deals, it's a take it or leave it situation. The price was low enough to roll the dice. Well, it's not a 700r4. It is a 2 yr only manual control 4l80e with a Mag hi Tec Pan, Converter, and flex plate. It has a 241 adapter on it but no actual matching t-case. The T Case that it came with, is a racetrack pattern 205 with the 32 spline input and Th400 adapter. Hmm. Do I sell it, or put a O/D in my diesel or wheeler. Either way, score! |

Re: 87 V20 D/D and Road trip Burb
Nice score! I would love to have one of those in my 6.2 Blazer, but the price of the trans, controller, and re-gearing the truck is a bunch of money I could never recoup. You've got a good head start though.

With a 91-92 4l80e, you don't need a controller. It is a manual shift setup. That now leaves me with 2 manual control 4l80e trans. 1st one is 2wd. For the wheeler project. 205 and black box will go on that one. 2nd is the factory 4l80e/251c combo. Score! |

Re: 87 V20 D/D and Road trip Burb
Nice score on the trans! Those mechanical ones have to be hard to be getting now I'm guessing?

They are getting rare. I only know that the 91 3/4 Burbs had them either 2wd or with 241 T-cases C/C 91's Came with 4l80e and a 205 I am not sure what they came in in 92 |
