Yes- they did offer a factory 2bubble, why, I don't know. I believe that even the 77 pace car replica was factory 2bbl. Olds still offered the Cutlass with a 455/4. And $4500 for a tow-it-away 77?? I don't think so- there are still too many of them around. There was one on ebay not too long ago with less than 12k miles and ttops- sold for about $10k- woulda bought it but it was mustard yellow with a matching interior-ugh!
