Been trying to figure this out, my Bride and I bought our 75 K20 new in June of 75. We don't have any of the paper work on and we ordered it. Took about 5 weeks and the MFG retail was somewhere around $6800 and my dealer cost was $5700?????? . Don't really remember.....our son was born a week after we took delivery(see what I did there).;) Things were a bit hectic at the time!!!!! Currently sitting in the shop yard across the alley, patiently waiting for me to get off my a$$ and change out the 350 engine.........it's a-7, lost number 7 cylinder. Right now it has 165000 on the clock.

@bucket I was working at the Chev-Cad dealership on the lube rack and the front end alignment pit when we bought this. Funny thing when it came in, there were 2 almost identical 75 K20 Gray/ Silver...whatever ..color pickups on the convoy. Mine and A guy I knew named John, brother of an old classmate. Mine was/is a 350/350/203/4.10 ff. His was a 400/400/203/4.10ff. At about 70000 I BBCed it with a 427. That didn't pan out and 350ed it at 80000. Now going back to original 350, .030 over, that has about 10000 miles on it. I had built it and put in my Chevy II and my Daughter drove it in her Sophomore, Junior and part of her Senior years in high school. Ought to be a good engine for the rest of my years. Probably only 500/750 miles a year use

Bought this from my grandpas estate for $100. He hadn’t driven it for 10+ years. I did a ton of work to it, rebuilt the front end, dress up pieces, ralleys etc.

Grandpa bought it from the original owner in 2001. So I’m the third owner of it. 350/350 diesel. Getting ready to overhaul the engine and keep this freak on the road for another 42 years.

That is a rare bird there! I know the 5.7 was an option in '81, but this is the first one I have ever seen. Super cool that you fixed up your Grandpa's pickup. What gear ratio is in that? Most had 2.73 or 3.08's, but 3.42's were an option. My dad had a '79 5.7 with 3.42's and he really liked it. He did say that the 5.7's didn't like to lug and that gearing them down helped them. I've often wondered how 4.11's with a 700R4 would be with that engine...

Very nice. What kind of mpg do you get out of that Olds diesel?

The Oldsmobile diesel is hated by many, but also has a cult following. Like anything else, they can be polished and refined into something pretty nice if someone is committed enough.

Not sure I’ll have to look at the sales codes… it likes to cruise at 60 mph so it can’t be a very high final ratio.

I think I posted in this thread once before but this happened today so I'm going to relay it for anyone that might find it interesting.

So I dropped the Jeep transmission off at the builder this afternoon, as Dan came out of the shop to grab the tranny out of the back of my truck, he stopped and said "is that the truck we build the 700 for you for?" I said yes and he asked if he could check it out and of course I said sure. A couple of his comments were "I had a completely different picture in my head when you said it was a work truck", "even the rockers are in good shape". He wanted to know when I bought it and what I paid for it. I told him I've had it about 5 years. I made him guess on purchase price. He said 12K. Gee, I said just about spitting my coffee out at him. I wouldn't own the truck if that were the case. "$800 was the purchase price". Yes, it ran, yes it needed work, yes I knew it was a deal, and most of all it came to me with good bones.

Here's what she looked like the day she came home.

I was going to ask him about doing my trans, now I'm not so sure. He might try to buy it! lol
He did not ask to buy my truck, just wanted to know what I'd pay for it, but you never know!

I've said this a couple times on the forum it has been a LONG time since I've owned a vehicle that I have gotten so into fixing up and driving and just loving than this truck. I'd probably have to go back to my teenage years. What I meant when I said I would not own my truck, is that I would not have paid 12K for it. Also at this point I'm not sure at what price I could be convinced to sell it at. I'm pretty deep into it in, and I'd likely never get this invested (time and money) into another truck.

It’s funny my other project is a Chevy II also.
