It all depends on how much money you are willing to spend..

Then i'd do either a full engine swap to a 3400 OR build a hybrid using the 3100/3400 heads on the 2.8. Toss in a H260-2 cam from Crane and a set of the "header" manifolds from a '04-05 Malibu (2 fronts). She'll scream then.
Of course you'll have to get into ECM tuning either way.

stock 3400 swap with the auto trans will put down about 150-160 to the wheels. With the hybrid i'd say about the same but it would make peak HP in the 6-6500 RPM range whereas the 3400 would be around 5500 RPM.
a 5 speed would be a nice upgrade with the stock 3400.. then you'd be just under 200 @ the wheels. and depending on how well you can drive and how heavy the car is that's a mid to high 14 sec 1/4 mile.
