Fuel Systems and Drivability / Re: Fuel System Picking up Air
« Last post by prider5 on Today at 06:01:43 pm »
Thanks for letting me know bd! I can make a new thread if you'd like.

Truck is 1977 K20, with a lot of parts from a 1980 K10. 350 SBC with a 1906 carb, and has dual tanks.

I've been rebuilding the truck, so it currently has 2 new fuel senders (dorman iirc), new tank switching valve, and just recently put a new mechanical fuel pump on (after having fuel delivery issues). I thought maybe the hard line had a hole somewhere, so I recently ran new rubber line from the switching valve up to the engine and made sure I ran it away from heat (thought it was potentially vapor locking), and back when I put the sending units in I ran new rubber lines before the valve as well.
I have a clear filter after the fuel pump before the carb, and I can see it pump fuel well when I first start it, and then after 10 minutes or so of driving the filter runs dry, with what looks like a lot of air bubbles flowing in as it runs out. Been struggling to figure out what the issue is, contemplating just putting an electric pump on it, but it would probably need to be after the switching valve, and I know they are notorious for not wanting to pull fuel and going out, so not sure. I think I tried it without the cap on as Vile suggested, but it's been a bit now and I'm struggling to remember for sure ha. I'll try this weekend if I can find the time to go and test.

Electrical / Re: TCC lockup pin location
« Last post by frotosride on Today at 01:32:15 pm »
Sorry been busy, my daily decided that power steering doesn't belong in the hydroboost anymore and while running the engine to prime the system the water pump decided to stop weeping and flood the driveway.

Anyway, yes I allowing the Terminator (not the x, but technically they are the same you just have to download a config and build a harness) to control the lockup via the (-) switching power for a relay. I'm doing this because within the config you can set many parameters and add inputs as needed to edit triggers. Also I can use TPS and not run another vacuum hose through the firewall. Having a vintage air set up helps that too

Engine/Drivetrain / Re: SM 465 to NV4500 Question
« Last post by Captkaos on July 09, 2026, 02:48:17 pm »
The NV4500 is longer than the SM465 by like a couple inches.  AND its hydraulic, so the bell would need to change and swap to hyrdo, the tunnel cover would need to be modified for length, driveshafts, the front would need to be longer and the back shorter.  output shafts are different on the driveshaft yoke.
This is just what I vaguely remember.  I think for this to work you need a early GM specfic trans, otherwise you need adapters since most were from a Dodge.

Good Times!  I hope  ;D
Well I was working on it with my twin brother but we discovered more problems than solutions.  I am trying to get this 1968 C10 that has been off the road since 2001 back on the road.
I got the Inline 6 running after rebuilding the carb and replacing most of the ingnition components and then discovered here was no driveshaft.
Since I wanted to actually drive it, I acquired a T5 and did a Jeep Shaft swap that we had hope to just do a pull and swap.  It really didn't work out as planned as we doing discovery on we pulled it apart. The bellhousing required a spacer that I didn't have, the retainer needed to be cut down, along with the pilot.  Then there was an issue with 20 year old wheels and no brakes.  I spent half the day trying to get fluid to all of the wheels.  Needless to say it is still up in the air, literally.

I updated your post to have the URL links so they aren't "lost" and I added one picture with the formatting. With Photobucket you need to open the image and copy the link.  All will be watermarked like the above. and if you ever loose them they will be gone like Kenny said.



sorry... I'd simply upload the photos but this site only likes jpegs with NO E.

Just download and rename them.

What you did to fix that needs to be in the Technical Pages Section.  That affects every square owner on here.

It actually is posted here: Annual Cleaning out the cowl

Blocked off cowl drain, to many leaves and the fan sucking them in and blowing into the AC box apparently into the resistor and creating ambers.
I haven't been consistent on cleaning out the cowl....

That's crazy!  Glad it turned out okay!

Don't give up.  Just upload the pics to here.  Gotta make em less than 500k  I feel your pain.  It's better than linking.  back in the day I used photobucket before they broke the entire internet.  I had hundreds of pictures linked on here.  they're all gone.  all i have left is what I've uploaded directly to this site.  I recommend doing that.  it will last in the long run.

Don't give up man!  We wanna see what you're doing!
