Not sure the 66 page on Team Chevelle will help with decoding a 70 body plate. (?)
Common mistake but the first line showing the series/model of 13680 does NOT indicate a V8 engine, only a trim level from Fisher Body. Bodies were made before any engine or other options were locked in by Chevrolet. The "22440" number is a Fisher Body tracking number and nothing to do with the car's VIN sequence number. In my GM parts book, 770 is simply listed as Antique Medium Saddle Coated Fabric (bench seat). I have photos of both an El Camino and 2-dr sport coupe on my site at http://www.chevellestuff.com/70velle/interiors/770.htm A paint code like 50 50 is a solid color for lower and upper body. Any vinyl or convertible top color would be designated with a letter in 1970. The BB0 (actually B80) and B90 are typical of Atlanta body plates where they put these two option codes (and really std equipment for 13637 coupes) for Roof Drip Molding (B80) and Door Window Frame Molding (B90). The 01D is the body assembly date, January, 4th week. The other numbers on the last line are data processing tracking numbers and can be found in various locations on the build sheet and are of no real significance today; except maybe to help spot phony build sheets. If the plugs come off the head at a 90-degree angle perpendicular to the head, they're straight plug heads. Angled plug heads are somewhere between 30 and 45 degrees from perpendicular. No Chevelles ever came with these heads that I'm aware of, but I'm not that up on angle plug head applications.
