Cut a one port out of a junk car and attach it under the dash. Wire some of the pins randomly to 12v and tell them to plug it in….or kiss your azz!Only ever had a more modern vehicle they just plug into, so this will be a new experience for me. I know the quadrajet is a fairly emissions friendly carb, and I've read that retarding the timing and upping the idle while leaning out the air fuel screws is the way to go. That and getting it good and hot by driving for an hour beforehand. But this truck also sat in a field for 15 years and she's only got so much to give.
Look in the glove box for the SPID sheet. It would also have a tag on the driver door frame with the GVW rating or inside the glove box. My door tags are gone, but I have the 8600GVW tag in the glove box. The rest of the story for the truck makes me think it is likely a California emissions truck. Especially since it came out of Arizona at some point. For $50, you can request the original vehicle invoice sheet for the truck by VIN number from GM Heritage. Based on what we have seen of the truck, I would expect the VIN to be CCS24"plant code""sequence number". If the Plant Code is an "L" or "Z", it's a California produced truck. My 1980 K25 with 8600GVW option was a Fremont, CA produced truck, but has the "NA5010 STD Emiss System" RPO code on the original invoice along with "F60028 H.D. FRT Springs".
Here is the 1979 Truck Vehicle Information kit. https://www.gm.com/content/dam/comp...its/chevrolet-trucks/1979-Chevrolet-Truck.pdf
Now that I'm looking at the vehicle information kit... it appears they didn't have an 8600GVW option in 79. I wonder if the emissions weight adjustment didn't kick in until '80? I know it was lower before, but it's surprising to me to see they only offered an 8200lb GVW option for the regular cab trucks.
$8000 is crazy town for that truck around here. You can get a much nicer one for that. Maybe he's wanting that because he dumped a bunch of money into new interior that he hasn't installed?
