While the wind is blowing too freaking hard and cold to want to go outside I dug this info out from the GM Heritage center website pfd for 57 Chevy. https://www.gm.com/content/dam/comp...information-kits/chevrolet/1957-Chevrolet.pdf that was found here where you can find the link for the pfd for most Early Chevy and up through 57 at least can find a lot of info including the specs on specific engines https://www.gm.com/heritage/archive/vehicle-information-kits. C is the suffix code for RPO 221 which is a 265 in 1957 C would be with a 3 speed, CD would be with overdrive and CE would have a heavy duty clutch. A 57 283 will start with E or F then extra letters for specific options.
Here are pictures of a 1957 265 block dated A227, the stamping before I had it decked was F205C. 3 spd. trans. This engine was in a 1956 Belair I purchased in 1980 when I lived in Detroit Michigan. Any chance they used them as dealer replacements? This is now .060 over and never run. I have no current home for it to go to. It was replaced with an LS.
I have one of our old E/class S.B. Chevrolet back up engines that Geisler bought from a kinda sketchy Bonneville racer years ago and that's kind of another story....anyway it is a standard bore 265 that has been sleeved down. It is a replacement block with a 1961 date code. It also has been decked so there are no deck numbers. So there were 265 replacement blocks available for years after they were discontinued in car/truck use. This block is pretty much a race only block, it has been O ringed and machined for 4 bolt mains and is headed for the scrap so if anyone here thinks they really need it, P.M. me and you will likely own it and if ya talk nice I might even throw in the splayed steel main caps with it.
