How are you liking the Dakota digital gauges? Do you have a boost and pyro? I've been looking into the cHx gauges with the bim modules but not sure where the additional readings are displayed?

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
The factory tach position has a digital readout that you can toggle through the extra outputs. Ryan also got an auxiliary display so he can see more than one.

The Longhorn got a room mate too. Ryan, here are a couple other pics of the back bumper that you asked for a while back.

I've been working on diagnosing the trans before I pull it out for repairs. The only weird thing is the front servo seems to have no pressure in reverse. All other pressures are fine. Out it comes.
I've been working on getting the corvette ready to go to the track next Friday night. My youngest brother is getting married on the 29th so the 28th for his bachelor's party he gets to take the car and make some passes. I just put taller front tires on it to gain some clearance. If you like Diesel World magazine, the car wil be in October or November's issue. |

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
Kjones, what what the pump off of? There are mods that can be made to the AFC to alow more travel out of it along with modding the diaphragm. My guess is that your fuel plate is pulled back and limiting full fuel or the AFC is to far back and not letting it fuel enough. The AFC housing is the only emissions equipment I ever liked. Set it up for a ton of fuel then dial it back till boost rises. Another thought is to ensure that you don't have a leak in the AFCs boost reference line or a faulty overflow valve (pressure valve in the return line). My 175hp pump and stock injectors would black out a lane of traffic when it had a stock turbo. 500HP has been hit with pump mods and a HX35 even though it was hot and smokey. You may want to reduce the timing a little. I ran 18-19* but always had head gasket issues even with studs and orings. 17* seemed pretty safe and spooled up a little better but power also dropped off earlier.

Kjones72, your timing sounds low to me for a P-pump 24v. Mine is set at 25*. I wouldn't go much lower than 23* personally. Sorry for the late response. I didn't see the new posts.
It may be too late to buy the mag off the stands now. The Vette was in Ultimate Diesel Builder's Guide October/November issue, instead of Diesel World. I had a hard time finding a copy a few weeks ago. It seems they were still on the racks last weekend though. As far as the Longhorn, the trans should be done at the trans shop this week. Hopefully in the next two weeks I can get it put back together. The engine has developed an oil leak. I need to fix that before I put the trans back in. I haven't had time to mess with it with work and helping a friend with harvest. |

Good job on getting in a magazine.

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
Today I picked the trans up from the trans shop. It should be fixed now. The engine has developed an oil leak. I need to remove the engine adapter and see where it is coming from. once that is fixed, then I can get back to installing the trans. Ten I need to finish a lot of things I haven't gotten too, to make it a daily driver. Like, mount the air compressor, tank, and leveling valve. Install and wire the compu shift mini, wire the heater circuit, wire in the cab lights, cargo and third brake lights, and check the operation of the wipers. I need to re-visit the LMC heated washer reservoir as I think that may be a nice addition too.

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
Same old stuff here. The truck has sat on the jack stands all winter out of the snow, ice, hail, rain, and even a tornado. Haha I've been acquiring more parts for it, and working on it when time allows. I managed to get my right and left seat belts in. A friend came over and worked on fitting the stereo to the billet radio mounting plate. He also hooked up the front speaker wires and mounted the speaker brackets I got from Bigblock73. I removed the brackets and painted them, then ran the speaker wires and reinstalled them. I also ran new wires to my cargo light and 3rd brake lights. Now I have to get a new cargo light switch to finish that. I also got my sill plates installed. Whoops, I almost forgot. I also installed my new precision push on door seals. I had to work them around pretty good with the rubber mallet to get them to fit end to end. Now the doors really shut hard but maybe they'll seal awesome. I also got the rear main replaced, and am picking up the expansion plug tonight that was my oil leak. I sent my torque converter in to get turned back into a diesel converter too. So when its back, I can get the trans put back in it. I'll try to add pictures later.

I forgot that I also ordered a 19gal Boyd aluminum tank. I had to have them change the mounting brackets, and it has a 1/2" feed instead of a 3/8". Now I have to decide on a side marker filler, tail light bed filler, or a bed floor filler.

Here are pictures of the new door weather stripping, sill plates installed with SS hardware, speakers, and seat belts. I also finally got my oil pan, rear main, and cam expansion plug all done. I also got a catch can for it. I think I'm going to mount it in the LH inner fender well. Now, once the torque converter comes back, I can put the trans and transfer case back in.

Looking Good! :metal: :metal:

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
Looks good! I guess I overlooked it, but what did the seat and seat belts come out of? Also, are the belts mounted in the factory hole in the b pillar?
|
Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
All looks very good!
I like the idea of side marker fill if you are wanting it hidden. |
