Don't forget that the original concept of the "odd-fire" V-6 was that is 
was a 90 degree design that allowed it to be assembled on the same line as 
the Buick V-8. This also allowed a "jump start" in 1975 while the 
2.8/3.1/3.4 Chevrolet 6- degree V-6 was being developed. However it really 
was not a very good small car engine but came into its own  for 
medium-large vehicles particularly when boosted. The 90 degree design 
allowed a very low hood. OTOH it had to be since for GM FWD, the engine is 
in front of the axle.

However the 3800 (really my favorite engine) has reached the end of its 
design life (particularly since it is an iron engine) and is now being 
phased out.

For some reason, GM tends to develop innovations too early then abandon 
just as they are perfected. The 4-6-8 was not a bad idea but really needed 
port fuel injection, an effective means to reduce pumping losses, and 
really fast response to changing conditions. This required modern computer 
controls that were not available at the time.
