Just the LT1 in the Corvettes and service replacement engines. All others are 2 bolt.

By the time it matters you should be looking at aftermarket caps anyway so no reason to worry about finding a 4-bolt block. The two bolt will hold a LOT anyway.

On most "average" builds the rod bolts are much more important to worry about then the mains. They are pretty much the most stressed part of the whole engine and have to deal with rediculous loads.
