Please note: Depending on the year of your engine, there are two Rod Bearing widths available. Most engines built prior to 1980 will use a 1.41" thick rod bearing. If your engine was built after 1980, you will need to measure the width of your bearing because both were used. There are also 2 different styles of main bearings. One style has an oil hole and an oil slot. The other has two oil slots. Also, some rod bearings did not have a center groove. This was added as an improvement and replaces the older non-grooved style.
