could someone please tell me how much the 3.4 L V6s and the 3.8 L are different. the 3.8 L is obviously faster, but by how much? and are there any other advantages of having one or the other?

They are two completely different GM engine families.
The 3.4 is from the notorious 2.8/3.1 Chevy 60-degree series first made in 1979 for the Monza.
Pros - It's light, and has solid journals for the rods.
Cons - Limited power capability, few performance parts, long-history of oil system problems, and head-to-intake gasket leaks.
The 3.8 was first debuted in the Buick Skylark (Monza clone) in 1975 and has powered every thing from Century station-wagons to Park Avenues, to the mighty Grand Nationals!
Pros - Far better reliability history, much more aftermarket support for parts. You can go nuts with the 3.8!
Cons - Split rod journals, but will safely take 350hp with a stock crank.
