    Kicking around doing an LS swap

    Thanks - I have to do some digging on my truck. It sound like the speedometer is driven off the transfer case and not the transmission like I thought.

    What is this wire / connector

    My googling told me it was the neutral safety switch too, but that was for manual trucks. So now for stupid question: If this is the NSS, how come my truck starts just fine? Is this just an extra wire GM left in a common harness? And finally, I thought on the '84, that the NSS was handled...

    Kicking around doing an LS swap

    I'm trying to figure out if an LS swap would be worth the effort. I have a 1984 K10 with a 350 and 700r4 trans and, I think, an NP205 transfer case. I'm not sure of my rear end gearing. I'm struggling with getting only 8 mpg no matter how I drive. I think an LS swap would give me between 12...

    What is this wire / connector

    This connector with the yellow / purple wires is located near the bottom of my steering column. "Near" is relative. its under the dash in that general area. I have a 1984 K10 with automatic trans (700r4). Thanks, Bruce. [edited to add picture.]

    Steering Column Refresh Oddities

    Fixed. The switch was sitting up higher than it should have been because I missed that the pivot of the switch has a cup that it fits in. I basically went back and re did the switch install and saw the cup sitting in the column

    Steering Column Refresh Oddities

    Found the horn honking issue: The brass ring on the back of the cancel cam is hitting the screw that holds the turn signal stalk to the switch. I tried filing the ring down, but that didn't work. Next step is to get a different, thinner screw and a different cancel cam. I'm open to suggestions.

    Overdrive not working

    If found this on another forum: The TH700R4 / 4L60 doesn't have a TCM. The test wire should have + voltage when the ignition is on and the TCC brake pedal switch and TCC vacuum switch are passing volts to the Torque Converter Clutch engagement wire on the transmission. There's no Serial data...

    Steering Column Refresh Oddities

    @Camar068 thanks for the link the document was really helpful. I watched a lot of Youtube videos, and this was one of the better ones: Good enough that the pictures i took now look pretty awful I got the column reassembled and a reproduction wheel on, which is now crooked. The wheel...

    Steering Column Refresh Oddities

    Replying to my own post - 1) There is a brass stud on the turn signal switch which contacts the back of the turn signal cancel cam. This is missing on the old switch. 30 minutes of cussing and disassembly and the old switch is out. @Goldie Driver -- thanks for the parts but the bit that I...

    Steering Column Refresh Oddities

    So, after some success with getting my reverse lights to turn on, I got cocky and decided to take off the little aftermarket steering wheel and put a stock replacement on. Now my truck does not have a steering wheel. First, I wrecked the spring clip and have to try to get another one. I'm...

    What have you done to your square lately??

    Played with the reverse switch and got it working. There were a couple of false starts - I tried to get the switch out but could not figure out how to do it. Rather than bust the switch, I kept playing with the adjustment, sliding it back and forth and finally got the reverse lights to come...

    Quadrajet Choke Operation

    @SirRobyn0 - great pic. The Weber carb on my bug has a very similar notched cam, but you can watch the cam click down as the carb warms up (I forget, but I am pretty sure it is an electric choke).

    Quadrajet Choke Operation

    Thanks all. I just expected that it would transition down to curb idle over time

    Quadrajet Choke Operation

    I am trying to figure out how the choke / fast idle work on a Quadrajet carb. Chevy 350 SBC, no EGR/emissions. Carb has electric choke which works. I set idle and high idle the other day to 750 and 1200. Today I started the engine cold: one pump of the accelerator pedal and a short spin of...

    Running Rich?

    Fixed the gas leak with yellow Teflon tape and moderate persuasion. Double and triple checked for no leaks Tried to time it again, and for the life of me I cannot see the timing mark at all. Gave up on that and adjusted the idle up to 750. Thought that I would go up to 850, but it just...

    Running Rich?

    @75gmck25: Thanks for your input. I fully closed the choke plate by hand yesterday and the engine stalled almost immediately, so I think we're covered on the vacuum leak. But that didn't stop me from spending time on youtube figuring out how to make a smoke generator to chase down a vacuum...

    Running Rich?

    Ok - tried to quickly check timing and I think it is set at 4* BTC, and I think the mark the shop made on the harmonic balancer aligns with the stock mark (an etched line across the balancer.) My problem seems to be that the pointer on the block pretty much covers the mark and is hard to see...

    Running Rich?

    It has been cold enough here to keep me from wanting to work on the truck for a bit, but I did install a fuel pressure regulator and set it to ~5.5 psi. Doesn't seem to have helped much, but I haven't done an actual check. The truck is running cleaner and the exhaust smells better though. I...

    Running Rich?

    I think it's mechanical secondary. There's no egr or cruise control hooked up. Heater/AC is after market and the vacuum ports were plugged. I'm going to have to track down any other possible leaks

    Running Rich?

    Thanks. Fuel pressure or wonky timing have been my suspected culprits. Just trying to do one change at a time so I can see the effects.

    What have you done to your square lately??

    Yesterday was just some simple stuff to make me feel better: Pulled the dash off to fix crackly speakers. I initially though it was bad polarity but Google thought it would be loose speakers. Fix is the same either way - get to the speaker and check polarity and tightness (polarity for the...

    Running Rich?

    It got cold and I got impatient, so I gave a trusted mechanic my truck and a list of things to do, including timing setting the idle. He said some things that were odd: First, he said that the timing mark on the harmonic balance was way off - like 50 degrees off so he estimated where TDC was...

    brake lights no worky!!

    Do you still have the old flasher? If you put it back in does the problem revert? You might have a bad new flasher [And its for that reason that I don't throw anything away until the job is successfully complete.]

    What have you done to your square lately??

    That's what I'm thinking. I'll investigate when I have more time / desire, but right now the solution seems to be "don't do that"
