For the past couple of years I've been looking for a service manual specific for the 1957 year Chevy 235 motor. I've been to swap meets, garage sales, flea markets and searched Craigslist, Ebay, and other internet sites but have not had any success. I'm looking for either an original or reprinted manual. I can find plenty of manuals for Chevy's 216 and 261 motors but not the 235. Any help is greatly appreciated!!! Thanks!!!
