This is a Partial Marine Base Engine (Par Pac), with a complete ignition and fuel system. The reason behind the Par Pac Power Packages were to address the customers who have a pre-Vortec (12 bolt intake) engine but want to upgrade to the newer style Vortec engine. Since the pre-Vortec engines utilized a different fuel and ignition system, these components are included with the power package while the components that you can re-use from your pre-Vortec are left out which saves you money in the end. Built only on GM Marine Engine Blocks, the partial power packages are manufactured to the same exacting standards as complete engine packages. These engines are built with the newer style Vortec 4.3L (8 bolt intake) longblock and have the following components pre-installed. Furthermore, every ParPac carries a Limited 1 year warranty on both parts and labor.
