I have a buddy that has a '97 370 with the 7.4 Horizon's and they are the half system. My '01 340 also has the same power plant w/ the half system as well.

Im a new 330 owner last season, tried to learn all I could. What exactly is meant by a half vs. A full system ? I have closed cooling systems as well.

The half system cools only the block with antifreeze.
The exhaust manifolds and riser elbows will be raw water cooled and need to be replaced every five years.

A full system will cool the block and exhaust manifolds with antifreeze but, the elbows are still raw water and will need the be replaced every five years.

Half system means only the engine block is plumbed into the system. A full system also includes the manifolds.

Here is a pretty informative writeup:
