We have found the main bearings and connecting rod bearing from a very large, early engine. The main bearings are 2 1/4" bore by 4 3/4" long and the connecting rod bearing is 2 1/2 bore and 2 1/4" wide. The connecting rod bearing halves are part # G329 and # G328. The main bearings are marked G325and are stamped 195 and 196. We were going to add pictures for clarity, but are not sure how to do this. If anyone might be able to help us and would like to see the pictures, please email us and we will try to send them to you through email. Thanks for any help that you can give us!
