1969 Pontiac Grand Prix 428: Barn Treasure

left front 69

This is a very original unrestored numbers matching 1969 Pontiac Grand Prix “J” with original paint. Since finding this in a barn, the owner has done a lot of work on it including new radiator, water pump, starter, fuel pump, headers, calipers, pads, hoses, master cyl, new rally wheels, new tires, motor mounts, shocks, alternator, hoses so it should be ready to rumble. It looks like they’ve added new headers as well. This is a well equipped Grand Prix with Posi-Traction, L79 428 engine, disc brakes, and optional gauges. I don’t see any rust, do you? It’s listed here on craigslist on Michigan’s Upper Peninsula, for a very reasonable $6,000. If this is as nice as claimed, this seems a real bargain. What do you think? A good polishing, some wax and a good cleaning of the interior could make this car amazing!

    Car should be an SJ. So it’s a J with a 428 added. Details, details…

    I’ve been looking for a 4spd one of these for years..
    On a side note the fishing in the U.P. Is amazing. Been going there my whole life-

    Incorrect or not, the want is strong with this one.

    Was 14 yrs old working in a local Esso station….the owner of the station purchased on of these from an elderly customer and it was used as a parts and lunch retriever. He used to let me go joy riding in it after …”no booze, no cops, have fun and bring it back in one piece..”..then he’d toss me the keys after he gassed it up….

    Don’t find bosses like that anymore….

    First burnout I ever did was in that car….

    It was an automatic just like this one….just jump on the gas and wait for the rear wheels to start spinning…

    fun car…wish it was closer…

    If all of that work was done, this seems like one good deal for
    6000.00 ?

    I bought a 1971 Pontiac Gran Prix in the early 80’s for $200 and it ran . It had a miss in the engine ( broken rocker arm ). Fixed the rocker arm and changed the oil and burned rubber all day long. The 400 cu.in. engine would cruise all day long at 120 mph. Long hood with a great ride and cold A/C. Dang I miss those days

    If all is like the seller claims, this is a good buy. The interior looks good. I only see scratches and dings in the body. This should clean up nice.

    One like this used to be on my “want one” list. That list keeps getting shorter and shorter and at times I don’t even want the ones I have now. LOL

    These were very nice cars in the early 70s. A little class and a little sport rolled into one.

    Oh hell yeah. Always surprised these are not more popular. They are subtly bad-ass.
    Nice price.

    Mum drove a Green 70′ with a 400 4 bbl. She was very often at or above 100MPH (those in Quebec with Cubic inches drove fast)

    What Walt said…..not sure about # matching but at that price and the looks good – could be the deal of the week…..the SJ’s are waaaay under-rated….

    I would love having this, codes matching or not. Have always loved these and the Monte that was based off this body style. Really don’t understand why they aren’t worth more. I do believe that the 428 was available in the model j. I know it was part of the sj package, but almost positive it was optional on the j. 4 speed cars are extremely rare.


    It does seem like a nice car. I’m surprised AC was not standard on any Grand Prix. I think headers is an odd choice, but that’s just me I guess. One concern, the seller mentions tons of parts replaced, but doesn’t mention internal engine work… but with the engine paint, I am pretty sure that engine has been out of the car.
    They are nice cars, and handled pretty good for their size.

    My dad ordered a model j with a 428 engine in it. It was an option available on either j or sj

    I bought this car.8/19/15
    I asked the owner to take photos of
    Block VIN# and head casting #.
    This was all after I sent him a deposit check because he didn’t do PayPal.
    He said to “Take his word for it” the numbers match! REALLY!
    I’m in N.C. He’s in M.I.His integrity aside I have no idea who this man is.So I explained this to him with the hopes that he would empathize with my position. This was not the case.”I am not getting under that car again.” I have walked away from this deal based on my gut instinct.To the best of my knowledge this car is now available again. It appears that he has remove the motor cleaned and painted it. This would make the numbers easy to see.seller is not willing to take two more photographs then the item is most likely not as described.

      That’s too bad Tom. Thanks for the update.

    • Jason

      “I am not getting under that car again.”

      You were right to walk away, Tom. I wouldn’t trust a seller who said that.
