Your Blazer looks awesome! Is the color code 508 dark blue on this blazer? I have a 1970 GMC Jimmy twin (converted 4x4) of this truck. I just got done wet sanding off the top coat of black paint to get back down to original paint/patina. Still very much a work in progress.

Thanks!
Yes, it is 508 Dark Blue, which is a one year only color. They used the same code before and after 1970, but the colors were a little different and 1970 only had a little metallic in it. When we replaced the driver's rocker my painter buddy shot it with their camera after polishing the Blazer and it came up as a match for a Navistar Fleet color. |

Re: Ratchet's Blazer - 1970 2wd with Original paint
That's good to see some recognition for your truck. Thanks for the paint code - that will help me down the road.
What did you end up doing with your old slot wheels? |
Re: Ratchet's Blazer - 1970 2wd with Original paint
The slots are still hanging out in the shop. I might put them on my S-10 Blazer since they are a car bolt pattern (5x4.75). Hadn't decided what to do with them yet.

Re: Ratchet's Blazer - 1970 2wd with Original paint
I drove the Blazer to a show last weekend about 2 hours away from my house. Once I got off the interstate, it didn't want to shift through the gears anymore. It pulled fine in gear, just didn't want to shift without winding it out in each gear and letting off of the gas completely. I ended up spending 6 hours on the road Sunday to drive home, get the diesel and the trailer, drive back to load the Blazer, then drive home and park it in the garage. I "believe" it may be the governor or some trash in the valve body, so that is this weekend's plans.
I am getting tired of the issues that I seem to keep having with this automatic, and I really didn't want to get rid of the manual in the beginning, I just wanted an overdrive. I have gotten a couple of quotes and I am leaning hard towards putting a TKO-600 in it and never have to worry about it again... except for a worn out clutch.;) |

I pulled the governor out of the trans yesterday and sure enough, the valve was sticking in it, as per the ASE YouTube mechanics' advice. I pulled the governor in the spare 700-R4 that I have and the valve in it moved freely like it should. It also had the VSS from the early 90's that still uses a speedo gear, so once I get a connector in for it, I can ditch the POS sending unit that Dakota Digital sent with their gauges, and I won't have to pull the tail housing to press on a reluctor wheel. So I may hold off on ordering the GPS module for now.
I put the governor in and the first few times it didn't want to shift until 4000 RPM, but once it went through all the gears a few times it seems to be acting normal again. It does seem like my TV cable is out of whack though, because the shifts aren't happening when they should based on how much throttle I'm giving it. I'll work with that, but it's looking good so far. All of these issues are still making me want to swap it to the TKO, though. So that is a definite swap that is coming in the near future. |
Re: Ratchet's Blazer - 1970 2wd with Original paint
I had so many trans issues with autos over the years. That’s why I stuck with the sm465 that came in my blazer. It is getting very sloppy after 40 years though and I’ll need to rebuild it soon but it hasn’t ever had a problem except the coupler breaking between the transmission and transfer case. Good you got it running and was a fairly simple fix.
|
Re: Ratchet's Blazer - 1970 2wd with Original paint
Yeah, I've thought about throwing the SM465 back in since I kept everything that came out, but I'm too used to having an overdrive now. I could add a Gear Vendors behind it, but it would cost almost as much as the TKO setup will, and it will still shift like a school bus. So I might as well go with one of the more performance oriented manuals. I'm pretty tired of the issues that come from automatics, so I'm sure all of my "toys" from now on will be a stick.
|
Re: Ratchet's Blazer - 1970 2wd with Original paint
Haha. Yep school bus shifting kinda sucks and no od does too. But I generally don’t go much over 60 in my blazer. If I still drive it long distances I’d want the od though. Having a six speed would be fun. And get much better mileage. But most of my trips are under a hundred miles either way.

Re: Ratchet's Blazer - 1970 2wd with Original paint
The tv cable is fairly easy to set.
Adjustment procedure (self-adjusting cable) 1. Stop the engine. 2. Depress the adjusting tab and move the slider back through the fitting away from the carburetor until it stops. 3. Release the adjustment tab. 4. Move the throttle linkage to rest against the full throttle stop, then release it . 5. Check the cable to insure that it is not sticking or binding. 6. Road test the vehicle. 7. If the problem still exists, refer to the cable diagnosis section. DIAGNOSIS A TV cable that is sticky; misadjusted, broken or incorrect for the vehicle can cause various transmission malfunctions. A sticky or binding TV cable can result in delayed or full throttle upshifts (figure 9). At other times, the TV cable may stick or bind only when the engine off. To check for this problem, run the engine at idle with the transmission selector in neutral and the parking brake set. Pull the end of the TV cable located on the throttle linkage, through its full range of travel, then release it. It should return to rest against the cable terminal (figure 10), it may be caused by one or more of the following conditions: 1. A sharply bent or damaged TV cable hosing. To correct this problem, try rerouting the cable. If this doesn't cure the problem, replace the cable. 2. A burr or sharp end on the TV link. This condition would cause the link to drag in the TV cable housing. You can correct this situation by filing the end smooth but Do Not shorten the link. 3. Misalignment of the throttle lever and bracket assembly on the valve body. Correct the alignment and torque the bolts to the proper specifications as noted in your service manual. 4. A bent TV link. Straighten or replace the link as required. 5. A binding or damaged throttle lever and bracket assembly. Straighten or replace the assembly as required. 6. An unhooked or damaged throttle lever spring. Reconnect the spring if it is unhooked. If it is damaged, replace the throttle lever and bracket assembly. 7. An incorrectly adjusted TV cable. (A) If the cable is adjusted too long, one of the following conditions may result: (1) early shifts, slipping, and/or no detent downshifts; (2) low line pressure. (B) If the cable is adjusted shore, or not hooked up at all, line pressure and shift points will rise and full throttle operation may not be possible. Hope that helps. |

I checked out the throttle cable situation and everything is definitely bent. I had made a bracket to bolt on top of the TV-Made-EZ bracket and it seems that that whole arm sticking out from under the carb is bent forward. I'll pull the carb off and straighten the bracket out, and I ordered a bracket that I might be able to modify enough to make it work to hold just the throttle cable. Hopefully that takes some stress off of the BTO bracket and doesn't bend it again.

Well, the BTO bracket was definitely bent once I got it off and had a chance to look it over. For a while, I didn't think that I was going to be able to use the bracket that I bought because the portion that drops down to clear the vacuum port and crosses over so that it can be held with the 2 back studs on the Quadrajet was hitting the runner on the intake. I eventually decided to grind until it fit and reinforce it after if I had to. To my surprise, it took way less grinding than I thought and no more reinforcing was necessary. I cut out the TV cable portion of the new bracket enough to clear the back of the cable adjuster, and I think it just might work. Then I scuffed up the gold plating real good and applied my favorite VHT Satin Black.
Now for the sort-of bad news... My throttle cable had to be taken apart to get it out of the old bracket and the cable itself frayed really badly which will make it very difficult to get it back together... IF it's not too short. The new bracket is further back than the old one by an inch, maybe inch and a half, so I'm afraid that my previously "cut-to-fit" might be cut too short. I've ordered another cable so that I can have it for next weekend after I get back from TX. Even if I can get the old one to work, I'll probably need the new cable when I switch to the Sniper. |

It took me a while but I got it all together. Since the bracket moved back towards the firewall and inch or so, I had to cut an inch out of the outer cable, which it needed, in order for the inner cable to be able to reach all the way to the carb linkage. It was not fun getting the frayed cable back into the pieces that it needed to go through, I don't want to have to do that again. I hooked up the TV cable and set it, then took if for a test drive... That 700-R4 must have heard me talking about throwing it away in favor of a TKO, because that SOB is shifting like it's supposed to now.
Next weekend I'll get the VSS in and wired so that I can have a speedometer again, see what I need to install the rear sway bar that I got from Wynne, clean it up and polish the damn wheels again. Then I'll be ready for our meet in St. Francisville! |
Re: Ratchet's Blazer - 1970 2wd with Original paint
Glad that all worked out. When it comes time for wheels, based on your experience, I’m looking into the clear cerakote...

Re: Ratchet's Blazer - 1970 2wd with Original paint
Does that dull the finish at all like a clear powder coat will?

Re: Ratchet's Blazer - 1970 2wd with Original paint
I looked it up and found their video on it. :lol: Apparently it can handle just about anything. I might have to look into that further.

Re: Ratchet's Blazer - 1970 2wd with Original paint
Can you take some pictures of your interior - I'm trying to determine the stock color of the dash pad, door arm rests and the column for my GMC Jimmy twin of your truck. I just went through your entire build thread and only saw glimpses of the interior spots noted.
Your Blazer looks awesome by the way! Well deserved recognition at the show. :metal: |
Re: Ratchet's Blazer - 1970 2wd with Original paint
Glad you figured out the trans problem. Must have been to much stress innit to bend it. Or just weak metal. Much easier to keep what’s there already if you can get it running correct.

The steering column is painted body color as they all were unless you had a factory tilt, which were all black. I've added some pictures that I have on my computer to show what I have right now, if you need any others, it will have to wait until I get home from TX again. Quote:

Re: Ratchet's Blazer - 1970 2wd with Original paint
Tge keeping it shiny part is why nothing on my truck is chrome anymore. Just black and blue with a white top. I went with Chevy bow tie seat covers in black. I also went with white painted wagon wheels on mine so all I gave to do is hose them off and wipe them with some mothers wax. Keeps them looking good and doesn’t let them rust. With yours the bigger chrome rims look decent. I just never liked the shiny look of chrome everywhere.

Thanks for the pix! I think I have a blue column in the stash somewhere - I think it is for auto though. I guess I can just pull the pin on the lever and remove it and use it that way it is so I don't need to find a blue manual column (yet).
I picked up this set of blazer bucket seats awhile back before I found a blue blazer for sale so I'll likely install these when the time comes. Just need to make sure the Jimmy came with sport buckets and not utility so I have the right floor mounting holes. |
Re: Ratchet's Blazer - 1970 2wd with Original paint
Mine had utility buckets, plus I am about 6' tall, so I did this...

Nice - I have a new mod to make on my blazers now.
If your Blazer is a 70 are they (extra set of holes and supports under the floor) on all models and years? I haven't looked under them for seat holes yet. Thanks for the pix and info! |

Mine only has the back set of holes for the utility buckets. I'm not sure when they started putting both sets of holes.

I also forgot to post up that Ratchet's Blazer also won a Top 25 award at a show a few weeks ago.

Re: Ratchet's Blazer - 1970 2wd with Original paint
Congrats on the win. Pinstripe looks very 70s retro. Cool
