You could order the microfiche report from Wayne Roberts. He has the film from the 2nd half of the year, Sloan museum has the first half, up until around January 1970.
SP = 315 High Performance 350. 10.5 to 1 compression. You should probably use premium. Sounds like a nice one!
It's really kind of cool information. A copy of the order form (not for your car, but like one used by dealers to order cars) a list of options installed by the factory, key codes, etc. I really don't know how much they cost now, but somewhere in the $100-$200 range.
You could also have SCO options that would be Buick and not Fisher Body, and wouldn't even get a low body #. Non-std. Rear axle ratio comes to mind, but there are others. Some of the taxi/police car equipment, etc. The '71-72 bucket seat verts I've seen all had SCO on the plate, but other SCO Fisher Body options (e.g. GSX) didn't. Here's a '72 with a special order color and the SCO chalk mark is clearly visible on the firewall. This is a Framingham car. I'd imagine it depended on the SCO option as to whether it was something that could've be done @ GMAD or whether it warranted that a car needed to be built in Flint. IIRC, weren't there even a few '72 GSX's built @ GMAD?
I know this is an old thread, but I ran across this info and am now curious. Since B80 seems to denote drip rail molding (based on the other info in this thread), was it possible to order a car with vinyl top and NO drip rail molding? I don’t believe I have ever seen one with a vinyl top that doesn’t have the drip rail molding and assumed it was necessary to assist in securing the edges of the top. If a vinyl top car has no “B80” on the cowl tag, does that mean it had no drip rail molding?
