P6 is a designation that applies to 4 cylinder models of every type and P6B applies only to the V8 with the B standing for Buick.
There are some physical differences in the mechanicals of the cars too such as tyre size, some suspension components and different diff ratio.
But perhaps the biggest difference other than the greater Torque and engine Power is the more esoteric quality such as the engine note and the dopamine affect of the huge smile you get when driving the p6B!
