Operating temps, now Buick V6 liniage

Hi Dave,
A great deal depends on how you define the term "fresh design"..
Actually, if you go a little furter back to 1964, you'l find a Buick Skylark 
V6
which had the same stroke and .059 smaller bore that the 80's 3.8RWD....
It also had the same bore and stroke as the 300 V8 of the day, which 
 was based on the tooling and bore centers of the earlier, smaller
displacement 215 aluminum V8..    Although the valve cover from a 1964 
Buick V6 was different, the head will bolt on the 1987 3.8 RWD engine...  
I think intake bolts are in differnt location, but I'm not positive on that...
The engine has seen significant design improvements and even 
changed hands in 1968, when it showed up in the jeeps.  It then went
back to GM, and was available in the some 1975 J-Bodies (Lordstown Plant), 
and then later in the GM intermediates again. Sh*t, I just showed my age
again..
