UGH! While tearing down my 261 I bent one of the rod cap bolts. Anyone know where I can get a replacement? I checked my stash of 235 parts- not a match. Another strange thing with this rebuild is the main bearings. I have a 1955-1957 motor, casting number 3837012. When I got the new main bearings they did not fit. The best way I can discribe it is that there is a notch on the block and a corresponding notch on the bearing. On my motor the notch is towards the front of the block but the caps were towards the back. I thought that the bearings were packaged wrong, but when I went to the parts store they looked it up (pictures) and found that the bearing I need is for a motor older than a 55. Whats up with that?
