Where is the best place to buy parts to totally rebuild a 235 ci, 1957. The head has been rebuilt but now we find the block is much worse than we thought. Maybe even buying a different engine would be better if anyone were willing to part with a good one, either a 235 or a 261. If anyone has one for sale and lives close to Wi. please let me know, if not let me know where the best place to get parts to do a rebuild on the block. Thanks.
