I have sometimes wondered why the 3.8 liter v6 seems to enjoy a better
reputation compared to GM's 3.1/3.4 liter offerings. On paper, the
smaller motors would appear to be a more rational design, due to the
60 degree bore spacing allowing for proper balancing without the need
for split crank pins, balance shafts, special motor mounts, etc.
I know about the lower intake gasket issues on these 3.1/3.4 motors.
Are there any other reasons to prefer the "v8 with 2 cylinders
missing" design of the 90 degree 3.8?? (other than bigger
displacement, of course)
