[Gmecm] 60° V6 Cam

[Jay Vessels]

Hi there!

V6/60 engines are defined primarily by the heads they have.  They're not 
referred to as "Series", but rather by generation.  The first generation 
V6/60 had iron heads.  The second generation V6/60 had aluminum heads 
and was only in FWD vehicles.  The third generation V6/60 has redesigned 
aluminum heads, roller cams, and more, and is the current V6/60 in 
production.  It is also only in FWD vehicles.

The V6/60 family tree is here:
