played with the throttle cable and kick down/detent bracket I like the way it turned out all aftermarket stuff except the accelerator cable so much easier with no fenders to lean over.....with my abused and old back

I like..... looking good

Finally finished rebuilding this with a kit from Cliff's High Performance. Waiting on a replacement spring for one of the air/fuel mixture screws. One of the springs disappeared. Hopefully it will be okay. Thought about getting another carb like this, a 7042210. My 1970 Chevy C10 Custom has a 350 as it always has, but this 350 came out of a 1973 Bel Air and the Quadrajet is a 1972 model with divorced choke. Still unsure if I should convert to HEI or not. She has a brand new American Autowire Harness in with more to install.

I have converted to HEI on 3 trucks and never regretted it.
Does the American Autowire harness have an HEI feed line?

If not you can get an HEI pigtail [Packard type dual connector 12 V to Coil/ Tach] from Jegs. Run a 12 ga wire from IGN Unfused on the fuse block to the Coil hot line. Disconnect the 20 ga Yellow lead to the points coil. Tape it off or delete it. it's connected to the Orange/Purple/White Resistor wire from the Bulkhead Connector. This line drops voltage to the Coil when heated. Less than full 12 VDC to HEI Coil will burn the Module up.

Many other posts about HEI conversion on this site, if mine was confusing.

Started the disc brake conversion on the 68 . Was a little worried the lower control arm would hit the wheel but it’s got plenty of clearance. Some before and after .

[72c20customcamper]

Changing all the ball joints the uppers were definitely original lowers not sure about . They wernt worn but the dust boots were shot .

I have been digging into the front end on my relatively new to me '69 1500 for the first time and there is a dust boot on a lower ball joint that is pretty shredded on one side. I was squinting at it and wondering if I could slap a little Flex Seal on it and forget about it for a couple years. How big of a job is is to change the ball joints??

Not a hard job with the right tools . The lowers pop out with a hand press I bought this one recently as my old one bent really bad doing my 3500 Dodge . The uppers if original I grind the rivet heads and drill them out a bit . If I had an air compressor I would use the air chisel . I’m doing this job at my rental property .

Yes the kit came with provisions for both, minus the resistor. If I do I will hang on to the old one just in case. Thanks for the reply!

I did the same on my '68 C/10 Stepside w/ 292 L6. I converted to Pertronix, using a points type Delco Remy L6 Distributor. But I did not rip out the points wiring. After about 7 years the Pertronix burned out. I went back to points operation for a year, until I had amassed all the right stuff for the rarer L6 HEI.

what points do you trust to put in these distributors? I'm leary of a lot of new stuff. But then you have the same with the unit that goes into the HEI distributor. I do IT and I LOVE mechanical over electronics lol.

Well, I haven't used points on either of my running trucks* in about 8 years.
[* '68 C/10 -- 292 L6; '71 GMC JIMMY K/1500 -- 350 V8]

I had a bunch of legacy L6 points and condensers. I liked Standard Blue Streak when I could get USA-made ones. The ''Asianization'' of replacement parts was one more reason to move to HEI.

There is more than one ''unit'' inside the HEI distributor.
- Module [Keep a spare in your glovebox, w/ the white insulator grease]
- Pick Up Collar and Harness
- Coil, Ignition
- Contactor ''Button'' from inside Coil to exterior cap Terminal Stud

I understand your preference for uncomplicated mechanisms over Electronic systems. I have a Feuerhand kerosene lamp on my back deck to illuminate my BBQ.

But GM HEI really is a performance upgrade.

[zicc1835]

tonight I layed out the cross sills and the bed strips so I could determine where the fuel fill will line up .....I want to put a round stainless fuel access hatch over the fuel cap IS 2.5 ROUND so I need like 4 inch access hole
ANY SUGGESTIONS ?
I bought this Boyd welding fuel tank years ago used... never had fuel in it couldn't pass up the deal so I will make it work

Did u buy the side markers used or find a vendor with them.

They were brand new from a vendor at the C10 fall festival. Dave’s truck parts

Now I guess I have to find one. What is a reasonable price for a functional one? What brand to get for replacement parts?

I diagnosed a fuel gauge problem (bad sending unit), reattached driver side vent window latch, un-seized and reinstalled the sun visors.

[1970cstblazer]

I was having an issue with the factory AM/FM radio in my Blazer. The volume would fade in and out, and sometimes would not come back at all unless you shut off the radio and turn it back on. The weakest link on these old Delco radios is the germanium output transistor. I noticed that a previous owner had replaced the output transistor with a cheap replacement, not a Delco part. I happened to have an old convector (amplifier) assembly from an early '70's Pontiac that had two original DS-501 Delco output transistors. I swapped one onto my radio, which on the truck/van AM/FM units is easily accessed in the aluminum heat sink on the side of the radio facing the passengers side of the truck. After swapping it out, I bench tested the unit, and it came to life, and the irregular volume was gone.

[72c20customcamper]

Coming along . And yes I cleaned the work area afterwards

looking good.... Im sure you will be happy with the performance of this conversion

[Steeveedee]

Yup, the difference in braking performance is worth it. Many will argue differently, but I'm on board with the pads wiping the rotors in the rain and making better stops due to less wet brakes. I'll have to say that drag racers may see an advantage in stock classes due to lower front brake friction with drum brakes, off the line...they tell me.

Shop: RockAuto, Jegs, Summit Racing.
I don't know what you'd find at your local junkyard.
When you look, add ten years later to your parts search, as there were no HEIs in 1968 [for example] so pretend you have a '78. Computers have a hissy fit if you try to get a more modern part for an older truck.
But you want the first generation of GM HEIs. Later ones have computer interfaces.

I hesitate to recommend AC Delco/Delco Remy anymore. They're now made offshore just like other Asian crap. Not worth paying more for the name with Americans unemployed.

Basic distributors seem to run about $75 at Jeg's.

I once bought a new [US-made] MSD Distributor Cap, and the contacts inside were too big. The rotor broke up hitting them. I don't buy MSD anymore.

I just looked up a '78 HEI at RockAuto. $186 for a reman Delco Remy. That's including core charge and NO Coil included. Forget them.
Tucson Craigslist shows one for $125. They say it's for an '85 Corvette! No thanks.
Summit seems very proud of theirs. Prices range from $97 to over $300.

Or look on the Parts Bord on this site.
Good hunting.
