I believe this may be the same car? https://rmsothebys.com/en/auctions/as14/auburn-spring/lots/r1058-1971-buick-gs-stage-one-455/577074 Discussed in the later part of this thread if it is that car. https://v8buick.com/index.php?threads/1970-gs-x-quartet.348754/
Is anyone close enough to take a look at the car? I asked the seller for a copy of the buildsheet and a pic of the trim tag.
David, There are a couple post (links) above talking about the car. From what I read back in 2021 No buildsheet. Trim tag: .
Thank you. I did not stay with the thread link above long enough to find the helpful info. Appreciated! I did contact the seller who provided these BS pix for all to enjoy I wonder what the worth is even if it is a nicely done clone. The cost of restoration drove me to sell my long-time project this summer and am shopping for a nice driver to take its place.
That the build sheet (Production Order Body Final - POBF) and if decoded would prove what the car was orig. Given there's no documentation avail for the '71s (yet anyway) that's one of the orig. docs that'll prove it.
Before shelling out anything for the car I would want to pay Duane to decode the entire sheet to verify how the car was born. The sheets found on the gas tanks are often for a different car but let's assume this one is indeed correct for this car, it does show a SE radiator which is for a big block car. Of course radiators are easy to swap and should never be used as a way to verify anything about a car.
I looked through a bunch of the photos I have collected of VINs stamped on Buick engines and while almost all of them were gang stamped, I did found some that were not. So I wouldn't automatically rule this '71 out as not having the original engine until it was inspected in person. Here is a '70 model that is original and was not gang stamped:
Thanks. I have reached out to Duane. Is there any credence to 71 documentation limitations and production inconsistencies? For example, the 71 I just sold had a quirky POP. The trans and axle codes lined up to S1, but the engine code was for a small block. The buyer seemed to expect this as a common strike year goof. (he has restored many other non-71 Buicks) I am not trying to reach on a verdict, I just know 71's have always been scrutinized ALOT.
First and foremost is to verify that this sheet is for THIS CAR. I've had my heart broken multiple times when I found a sheet on a tank just to learn that it was for a different car. For a fee Duane can use some of these boxes to help rule out if this thing is a real Stage 1. Duane knows the '71s really well since he has one and has studied them very closely. The part number for the frame will indicate if it was a small block or big block originally, but will not tell if it is a Stage 1. So verifying big block is much easier than verifying Stage 1. Frame for a '71 350 coupe is 3992388 CR Frame for 455 or Stage 1 coupe is 1237139 BA But looking at the old thread shows that it has a numbers matching OW code transmission which is for a '71 Stage 1. The rivet holding the OW tag in place appears to be an original. This is pretty good proof that this one is an original Stage 1.
