    Default 5.3L engine has 4 bolt mains?

    I was looking around on the net and apparently the 5.3L engine in the Silverado/Sierra has 4 bolt main caps. Can anyone confirm this?

    Thanks.

    Default

    Actually, the LS style engines have six bolt mains. Four are vertical and two are horizontal and come in from the side of the block.
