How to Assemble the Front of a Small Block

The bolt with the hole in it was only used on early motors and did not have the dripper then. The dripper was a more effectiv oiling method used on later motors and got its oil from the oil run off or overflow from the front cam bearing. The combination of the two is a good Idea and I have done this. But it is not nessasary. I have factory bolts like this and can also make them from Grade #8 bolts in the lathe if needed .Steve
